In the world of ultralight backpacking, the philosophy is to carry only what you need and nothing more. In this blog post, I'll explore the various options for ultralight backpacking gear available at REI Co-op, a trusted retailer for outdoor lovers. For those new to ultralight backpacking or transitioning from a traditional heavier setup, REI is a great starting point due to its wide selection of quality gear, customer-friendly return policies, and knowledgeable staff. Whether you’re a seasoned ultralight backpacker or just starting to lighten your load, this guide will help you navigate the essentials for a more enjoyable and efficient hiking experience.

Why Go Ultralight?

The philosophy of ultralight backpacking is simplicity and efficiency. It's about bringing only what you truly need and nothing more. This approach not only reduces the weight of your pack but also minimizes clutter and simplifies decision-making on the trail. By carrying less, you can hike longer distances with less strain on your body, making your backpacking trips more enjoyable and less tiring. The lighter load allows you to focus more on the beauty of your surroundings, rather than the burden of a heavy pack.

Why Choose REI Co-op for Ultralight Gear

REI is a great place to start your ultralight journey for various reasons:

  • Flexible Return Policy: One of the biggest advantages of shopping at REI is their return policy. If you try out your gear and find that it doesn't work for you, you have up to 1 year to exchange it or get a refund if you’re an REI member. This gives you the freedom to experiment with different gear options without the risk of being stuck with a piece of gear that doesn’t work for you.

  • Convenience & Simplicity: Starting your ultralight journey can be overwhelming, especially when navigating through numerous cottage gear companies. At REI, you can find a wide range of ultralight gear all in one place, making it easier to compare and choose the best options for your needs.

  • Try Before You Buy: Unlike many online-only retailers, REI allows you to try on gear in-store. This is particularly important for items like backpacks and shoes, where fit and comfort are crucial. You can also get measured for a pack to ensure the correct fit.

  • Durability and Reputation: Products available at REI are generally known for their durability and quality. They carry gear from widely recognized and trusted brands, giving you confidence in your purchases.

  • Expert Advice: REI staff are often outdoor enthusiasts themselves and can provide valuable advice and insights to help you make informed decisions about your ultralight gear.

  • REI Member Benefits: If you're an REI Co-op member, you can take advantage of additional perks such as using any REI Co-op Member Rewards you have, applying discount codes, or shopping during REI sales. These benefits can help you save money on your ultralight gear purchases. If you haven’t already, I recommend purchasing the one-time $30 lifetime membership at REI Co-op, which gives you access to member-only coupons, discounts, 10% back on eligible purchases, and more. I became a member back in 2018, and I always look forward to the coupons and receiving my annual rewards every year.

REI has a lot of good ultralight gear options; however, REI might not have the absolute lightest gear compared to cottage gear companies. What makes REI a great place to start is its return policy, the durability/reliability of its products, and the knowledge of its staff, which all can help simplify your transition to lighter-weight backpacking.

How to Use This Guide

Embracing ultralight backpacking does not require you to replace all your gear at once. It's about making strategic choices where you can save the most weight. For example, if you're currently backpacking with a 5lb tent, switching to a lighter tent can make a significant difference. Similarly, if you have a heavy sleeping bag, opting for a lighter option could save you a couple of pounds. The key is to prioritize and gradually build your ultralight kit.

Use this guide as a starting point to explore ultralight options and make informed decisions based on your needs and preferences. It's a resource to help you understand the trade-offs and benefits of different gear choices. You don’t need to replace all of your gear at once, instead, focus on a category that would most improve your current base weight.

Please note that this guide does not cover every single piece of gear you need for a backpacking trip. It focuses on the main categories such as backpacks, sleeping bags/quilts, sleeping pads, etc. For a comprehensive list of all the gear you need to go backpacking, including clothing, electronics, and first aid kits, check out this blog post: Backpacking Essentials: All the Gear You Need for a Backpacking Trip.

Using What You Already Have

Don't forget to use the gear you already have. Not everything needs to be ultralight to start. As you gain more experience and understand your needs better, you can gradually replace items with lighter alternatives.

Gear Categories

I’ve organized this guide into the following categories if you’d like to jump ahead to a particular section:

My Overall Ultralight Gear Picks From REI

For a very brief overview, if I had to choose a single item from each category for my ultralight backpacking setup from REI, here's what I would select (read entire post to learn about additional options for each category):

These are the items I would choose based on my preferences for weight, comfort, and functionality. Your choices may vary depending on your specific needs and the conditions you expect to encounter on your backpacking trips. I’ll go into the reasons why I would chose each of the above options in the sections below. Continue reading to learn about additional options available at REI for each of the above categories.

Backpacks

When selecting a backpack, consider your individual preferences and specific needs, such as overall gear weight, trip duration, and personal comfort. Make sure to align the backpack's maximum load recommendation and volume capacity with your backpacking gear. For example, if you're carrying a relatively lighter load (<10 lbs base weight), opting for a pack with a smaller volume and lower maximum load recommendation may be a good option. Conversely, if your gear kit is on the heavier side, a backpack with a higher volume and maximum load recommendation would be a better option to meet your current needs.

I generally try to keep my base weight, which is the weight of all my backpacking gear not including consumables (food, water) or worn clothes, about 10-15 lbs under the max load recommendation, leaving those last 10-15 lbs for food and water.

Some of the packs below have adjustable options, allowing them to carry different amounts of gear comfortably. For example, the Hyperlite Mountain Gear Southwest packs feature a roll-top closure that can be adjusted to securely accommodate varying amounts of gear, making them versatile for trips with different gear requirements. The Osprey Eja 48 Pack (Women's) and Osprey Exos 48 Pack (Men's) both have a “brain” that you can remove to shed some weight if the additional space isn’t needed. Both options allow flexibility of your current gear weight, making them versatile options.

Here are some great backpack options available at REI:

Product Weight Price Volume Max Load Recommendation
Hyperlite Mountain Gear Southwest 55 Pack 🔗 32.5-37.2 oz $379 55L 40 lbs
Hyperlite Mountain Gear Southwest 40 Pack 🔗 29.7-34.9 oz $349-$369 40L 40 lbs
Osprey Eja 48 Pack (Women's 🔗) / Osprey Exos 48 Pack (Men's 🔗) 43-46 oz $240 45-51L 25-30 lbs
REI Co-op Flash Air 50 Pack (Women's 🔗 / Men's 🔗) 28-31 oz $299 49-51L 25 lbs
REI Co-op Flash 55 Pack (Women's 🔗 / Men's 🔗) 42-46 oz $199 53-57L 30 lbs

Descriptions of each backpack:

  • Hyperlite Mountain Gear Southwest 55 Pack:

    • Ultralight and durable pack made from Dyneema® Composite Fabric (“DCF”).

    • Designed for long-distance backpacking and thru-hiking, but is a great option for shorter backpacking trips, too.

    • Water-resistant with a roll-top closure and multiple external pockets for easy access to gear.

    • This pack is probably the most versatile pack from this list. Yes, it's the most expensive, but it is also made out of higher-quality materials and should be more durable than the other packs. Getting the 55L version will allow for additional space if you have some gear with more volume, but it can also pack down small if you don't use all the volume. It comes in both black and white colors, but the white color is lighter.

  • Hyperlite Mountain Gear Southwest 40 Pack:

    • Compact version of the Southwest 55, ideal for shorter trips.

    • Same durable construction and water-resistant features as the larger model.

    • If you know you'll never need more than 40L, then opt for this size.

  • Osprey Eja 48 Pack (Women's) / Osprey Exos 48 Pack (Men's):

    • Features a suspension system for ventilation and comfort that creates airflow between you and your pack.

    • Removable brain and multiple pockets for organization.

    • Offers a balance of comfort, ventilation, and weight savings.

    • My partner, Tim, used an Osprey Exos Pack for his thru-hikes of the John Muir Trail and the Pacific Crest Trail. He liked how well this pack carried weight and thought it was a great beginner ultralight backpack.

  • REI Co-op Flash Air 50 Pack (Women's / Men's):

    • Ultralight and versatile pack with a focus on weight efficiency.

    • Adjustable torso length and load-lifter straps for a customized fit.

    • Roll-top closure and removable top lid for flexibility in packing.

    • This is the most ultralight pack that is currently available at REI Co-op. This would be a good pack if your base weight is very low (<10 lbs).

  • REI Co-op Flash 55 Pack (Women's / Men's):

    • Lightweight and customizable pack with modular components for personalized setup.

    • Features a ventilated back panel and hip belt for comfort.

    • Multiple pockets and attachment points for organized gear storage.

    • This is a popular pack for backpacking and thru-hiking.

    • This is the most budget-friendly option, but is not the lightest out of the selection here.

Out of all of these packs, I would choose the Hyperlite Mountain Gear Southwest 55 Pack as a starter ultralight backpack because it is made out of the most durable and premium materials (DCF), has additional volume if you need it but can also pack down small when you don’t need the extra volume, and has a higher max load recommendation of 40 lbs, which is nice for a range of base weights. Also, I would choose the white version of the backpack because it is a slightly lighter material than the black fabric, but do note that the white will get dirty overtime.

Sleeping Bags/Quilts

When selecting a sleeping bag or quilt, you’ll want to look for an appropriate temperature rating for the environment you’ll be camping in, check for a decent fill power of 800+, and see if the materials are lightweight and durable. I strongly advocate using a quilt instead of a sleeping bag to save weight. A quilt is basically a sleeping bag without a back or hood. Why a quilt instead of a bag? Because when you sleep in a down sleeping bag, the back of the bag is fully compressed from you laying on it and the compressed down is not insulating, thus it might as well not be there so you can save some weight. Instead, for insulation on the bottom you use your sleeping pad. Not sold on a quilt? That’s okay, I also include a couple of sleeping bag options below.

Product Weight Price Temperature Rating Fill Power
REI Co-op Magma 30 Down Trail Quilt 🔗 20.3-24.5 oz $329 30°F 850
REI Co-op Magma 30 Sleeping Bag 🔗 21.6-27.8 oz $379 30°F 850
REI Co-op Magma 15 Sleeping Bag 🔗 32-43.3 oz $429 15°F 850

Descriptions of each sleeping bag/quilt:

  • REI Co-op Magma 30 Down Trail Quilt: Versatile and lightweight quilt, ideal for backpackers who prefer the flexibility of a quilt over a traditional sleeping bag. High-quality 850 fill power down provides excellent warmth-to-weight ratio. Rated for temperatures down to 30°F.

  • REI Co-op Magma 30 Sleeping Bag: Mummy-shaped sleeping bag with a focus on warmth and comfort. 850 fill power down ensures lightweight insulation. Rated for temperatures down to 30°F.

  • REI Co-op Magma 15 Sleeping Bag: Designed for colder conditions with a temperature rating of 15°F. High loft 850 fill power down provides superior warmth and compressibility. Heavier than the Magma 30 options, but offers increased warmth for colder nights or high-altitude adventures.

Out of all these options, I would personally select the REI Co-op Magma 30 Down Trail Quilt because I am a quilt user and this is a great starter quilt.

Sleeping Pads

When it comes to sleeping pads, there are two main types: closed-cell foam pads and inflatable pads.

Closed-Cell Foam Pads: These pads are made from dense foam filled with tiny closed-air cells. They are usually lightweight, very durable, and less expensive.

  • Pros: They are nearly indestructible, provide decent insulation, and can be used as a sit pad or frame in frameless backpacks. They're also easy to use since there's no need for inflation.

  • Cons: They tend to be bulkier and less comfortable than inflatable pads. The foam can also compress over time, reducing insulation.

Inflatable Pads: These pads are made from air-tight materials that can be inflated to provide cushioning. They often have internal baffles/chambers to enhance comfort and insulation.

  • Pros: They are more comfortable and compact than foam pads when packed. Many have higher R-values for better insulation and are typically warmer.

  • Cons: They are more expensive, can be punctured (requiring repair), and may require more time to set up (inflation). Every inflatable pad I've owned has required repair due to holes, but they are more comfortable and warmer.

Closed-cell foam pads are a budget-friendly and durable option with moderate insulation, while inflatable pads offer more warmth, comfort, and compactness at a higher price point and with a bit more care required. The choice between the two depends on your priorities, such as weight, comfort, durability, and insulation needs.

In the context of sleeping pads, the R-value measures its ability to insulate and resist heat flow. The higher the R-value, the better the pad's insulation properties, which means it should keep you warmer in colder conditions. R-values typically range from 1 (minimal insulation) to 10 (maximum insulation), but most three-season pads fall between 2 and 5.

Here are a few ultralight sleeping pads available at REI:

Product Weight Price Closed-Cell Foam/Inflatable R-Value
Therm-a-Rest NeoAir XLite NXT Sleeping Pad 🔗 12-17 oz $199.95-$239.95 Inflatable 4.5
NEMO Switchback Sleeping Pad 🔗 10.5-14.5 oz $44.95-$54.95 Closed-Cell Foam 2
NEMO Tensor Ultralight Insulated Sleeping Pad 🔗 14.5 oz $200 Inflatable 4.2
Therm-a-Rest Z Lite Sol Sleeping Pad 🔗 10-14 oz $47.95-$57.95 Closed-Cell Foam 2

Descriptions of each sleeping pad:

  • Therm-a-Rest NeoAir XLite NXT Sleeping Pad: Ultralight and compact design. High R-value provides excellent insulation for three-season use. This is my favorite sleeping pad. I used a NeoAir Xlite on the John Muir Trail, Pacific Crest Trail, Arizona Trail, and most of the Continental Divide Trail. I like that it is lightweight, comfortable, and has an R-value of 4.5, which essentially means it helps keep you warmer. This sleeping pad comes in various lengths, so choose a length appropriate to your height.

  • NEMO Switchback Sleeping Pad: Durable and lightweight foam pad. Closed-cell foam provides basic insulation and cushioning. Accordion-style design allows for easy packing and setup. I used this for all of New Mexico on my Continental Divide Trail thru-hike. The nice thing about foam sleeping pads is that you don't have to spend time inflating them when you get to camp. You can just pull it out and lay down, which is so nice when you're exhausted at the end of the day. It's also nice for taking breaks throughout the day. It comes in two different lengths, but you can also cut it down to whatever size you like (which I did).

  • NEMO Tensor Ultralight Insulated Sleeping Pad: This is a another popular inflatable sleeping pad. Lightweight and comfortable, suitable for three-season backpacking. Insulated for warmth, with an R-value that balances weight and insulation. Spaceframe baffles provide stability and support.

  • Therm-a-Rest Z Lite Sol Sleeping Pad: Also comes in a yellow color. Versatile and durable foam pad. Closed-cell foam offers basic insulation and cushioning. Accordion-style design for easy packing and deployment. The foam pattern is slightly different than the other one. This sleeping pad similar to the other one listed.

Out of these sleeping pads, I would choose the Therm-a-Rest NeoAir XLite NXT Sleeping Pad. This has been my go-to sleeping pad for 4+ years and I would choose it again and again. I prefer this sleeping pad because it is inflatable which makes it more comfortable, it has the highest R-value out of the below options, and it comes in different lengths so you can choose a length that is suitable to your height.

Tents

When choosing an ultralight backpacking tent, here are some key terms:

  • Tent Trail Weight: The trail weight of a tent refers to the minimum weight of the essential components needed to set up the tent, typically including the tent body, rainfly, and poles. It does not include additional items like stakes, guy lines, or stuff sacks, which are considered part of the tent's packed weight.

  • Semi-Freestanding vs. Freestanding Tents:

    • Freestanding Tents: These tents can stand on their own without the need for stakes or guy lines, thanks to their pole structure. They are easy to set up and move around, making them popular among backpackers. However, they tend to be heavier due to the additional pole material.

    • Semi-Freestanding Tents: These tents require some stakes or guy lines to set up properly, as not all parts of the tent are supported by poles. They are usually lighter than fully freestanding tents, making them a good choice for ultralight backpacking.

  • Tent Capacity:

    • 1-Person Tents: Designed for solo backpackers, these tents are the lightest and most compact option. They provide just enough space for one person and their gear.

    • 2-Person Tents: These tents are suitable for two people or for a solo backpacker who wants extra space for comfort or gear storage. They offer a good balance between weight and space for most backpackers.

    • 3-Person Tents: Ideal for small groups or couples who want more space, these tents are larger and heavier, but provide ample room for three people or two people with extra gear.

Choosing between these options depends on your priorities, such as weight, space, convenience, and the number of people sharing the tent. Each of the following tents offers a different balance of weight, space, and features, making them suitable for various types of backpacking trips.

Product Capacity Trail Weight Price Type
Big Agnes Tiger Wall UL 1 Solution-Dyed Tent 🔗 1 person 30 oz $399.95 Semi-freestanding
Big Agnes Tiger Wall UL 2 Solution-Dyed Tent 🔗 2 person 35 oz $449.95 Semi-freestanding

NEMO Hornet OSMO Ultralight 3P Tent 🔗 3 person 45 oz $549.95 Semi-freestanding
Big Agnes Copper Spur HV UL1 Tent 🔗 1 person 34 oz $429.95 Freestanding
Big Agnes Copper Spur HV UL2 Tent 🔗 2 person 43 oz $529.95 Freestanding
Big Agnes Copper Spur HV UL2 Tent - Long 🔗 2 person (long) 46 oz $579.95 Freestanding
Big Agnes Copper Spur HV UL3 Tent 🔗 3 person 56 oz $579.95 Freestanding
Big Agnes Copper Spur HV UL3 Tent - Long 🔗 3 person (long) 57 oz $629.95 Freestanding

Descriptions of each tent:

  • Big Agnes Tiger Wall (UL 1/ UL 2 / UL 3): The Tiger Wall is an excellent ultralight backpacking tent option. The main difference between the Tiger Wall and the Fly Creek is that the Tiger Wall has a side door entrance (easier to get in/out of) whereas the Fly Creek has a front door, which is harder to get in/out of. Both are semi-freestanding tents.

  • Big Agnes Fly Creek HV (UL 1 / UL 2 ): The Fly Creek is lighter than the Tiger Wall, but has a single front door entrance, which can be hard to get out of or may not be preferable with 2+ people.

  • NEMO Hornet OSMO Ultralight (1P / 2P / 3P): The NEMO Hornet is a comparable tent to the Big Agnes Tiger Wall line and also has a side door entry, just with slightly different features, a slightly lower price, and a slightly lower weight. The floor space and vestibules are also smaller on the Hornet.

  • Big Agnes Copper Spur HV (UL1 / UL2 / UL2 - Long / UL3 / UL3 - Long): The Copper Spur is a great option for a fully freestanding tent. It is a bit heavier but could be worth the extra weight if you want a true freestanding tent. This tent also has a side door entry.

If I had to choose one tent out of the following options as a starter ultralight backpacking tent, I would choose the NEMO Hornet OSMO Ultralight 1P Tent because it has a side door entry, is a relatively low weight, and is a solid solo backpacking tent.

Pillows

While some consider a pillow a 'luxury item' for backpacking, I believe it's essential for a good night's sleep. I believe that quality sleep is essential for an enjoyable backpacking experience. I typically try to choose a pillow that weighs 2-3 oz. Each of these pillows offers a different combination of comfort, weight, and packability, making them suitable for various types of backpacking trips.

Product Weight Price Type
Sea to Summit Aeros Premium Pillow 🔗 2.7-6.9 oz $54.95-$69.95 Inflatable
NEMO Fillo Elite Pillow 🔗 3 oz $59.95 Inflatable
Sea to Summit Aeros Ultralight Pillow 🔗 2.1-4.6 oz $44.95-$64.95 Inflatable
Sea to Summit Aeros Down Pillow 🔗 2.5-6.7 oz $64.95-$89.95 Inflatable
Rumpl Stuffable Pillowcase 🔗 3.2 oz $40.00 Stuff sack

Descriptions of each pillow:

  • Sea to Summit Aeros Premium Pillow: Offers adjustable firmness for personalized comfort. Brushed polyester outer provides a soft feel against the skin. Available in multiple sizes to suit different sleeping preferences. I used this pillow on the John Muir Trail and liked it a lot. It is slightly more comfortable than the Aeros Ultralight Pillow, in my opinion. I typically get this pillow in the Regular size.

  • NEMO Fillo Elite Pillow: This is another inflatable pillow option, but this one is not as tall as the other inflatable options. The Fillo Elite Pillow is 3 inches tall, whereas the Sea to Summit pillows are all at least 4.3+ inches tall. This is something to consider if you are putting your pillow on top of your sleeping pad or on the ground above your sleeping pad. Features an integrated stuff sack for easy packing and storage, and it is machine washable for easy cleaning.

  • Sea to Summit Aeros Ultralight Pillow: Even lighter than the Aeros Premium, making it a great choice for ultralight backpacking. The ergonomic shape supports the head and neck for a comfortable sleep. I used this pillow on the Pacific Crest Trail, Arizona Trail, and most of the Continental Divide Trail. It isn't the most comfortable, but I'm also not very picky. I chose this one because it was slightly lighter and cheaper than the Aeros Premium.

  • Sea to Summit Aeros Down Pillow: This is an inflatable pillow with a soft, down-filled cushion top. Combines the comfort of down with the support of an inflatable pillow. The down layer provides extra warmth and softness. Compact and lightweight, with a luxurious feel.

  • Rumpl Stuffable Pillowcase: The versatile design allows you to stuff it with clothing or a jacket to create a pillow. Made from the same material as Rumpl blankets, providing a soft and cozy feel. Lightweight and packable, with a water-resistant exterior.

Out of these pillows, I would choose the Sea to Summit Aeros Ultralight Pillow in the Regular size because it is only 2.1 oz, making it the lightest and cheapest inflatable option.

Stakes

All the tents listed in this post come with stakes, but I prefer switching out my stakes to ones that are more durable and lighter. This is probably an unnecessary gear change if you are just starting out, but I recommend the following stakes if you need to replace lost/broken stakes or are extremely gram-conscious:

Product Weight Price Notes
MSR Mini Ground Hog Stake 🔗 0.35 oz $4.50 Smaller/lighter version of the Ground Hog stake. I like these stakes to use along the sides of shelters.
MSR Ground Hog Stake 🔗 0.5 oz $4.95 I use the larger version of the stake to use as sturdier ridge/main stakes.

Puffy Jackets

When selecting an ultralight puffy down jacket, prioritize high-quality down insulation and consider a higher fill power for an optimal warmth-to-weight ratio. Consider the following when choosing a down jacket:

  • Fill Power: Aim for a higher fill power for superior loftiness and insulation efficiency. The difference between fill powers, such as 800 and 850, lies in loftiness and insulating efficiency, with a higher number indicating superior performance. I typically look for a down jacket that has 800 or 850 fill power.

  • Weight: The weight of the jacket will depend on what size you get, but my goal is to try to keep the jacket under 1 lb (as long as it has 800-850 fill power). You want to ensure it is still warm, but also not super heavy.

  • Design: Look for a lightweight and packable design.

  • Water Resistance: Opt for a jacket with a durable water-repellent (DWR) coating to enhance water resistance.

  • Hood: I like down jackets with a hood, just in case I need to sleep with it on in really cold conditions or hang out at camp when it’s chilly outside.

  • Durability: Check the outer shell material for durability. This will typically be indicated by the denier of the fabric. A lower denier means it’ll be slightly less durable, but it will be lighter. I don’t mind my jackets being a bit more fragile with a lower denier, making them lighter, but that is a tradeoff I’m fine with.

Descriptions of each jacket:

  • Mountain Hardwear Ghost Whisperer/2 Down Hoodie (Women's / Men's): Ultra-lightweight and packable, made with 10-denier fabric. This is a very popular backpacking and thru-hiking down jacket.

  • REI Co-op Magma 850 Down Hoodie (Women's / Men's): More budget-friendly option with high-quality 850-fill power down for superior warmth. Slightly heavier but provides excellent value for the price. Simple design with focus on warmth and comfort. I've been using this jacket recently and think it is a great budget down jacket option.

  • Arc'teryx Cerium Down Hoodie (Women's / Men's): Premium option with a mix of down and synthetic insulation for optimal warmth and moisture resistance. 850-fill power down provides excellent warmth-to-weight ratio. Outer fabric is 15-denier, lining fabric is 20-denier. Combines lightweight construction with high-performance insulation. Hybrid insulation ensures warmth in wet conditions. This has been my go-to backpacking jacket for the past few years.

Out of all these options, the most ultralight option is the Mountain Hardwear Ghost Whisperer/2 Down Hoodie (Women's / Men's). This jacket has a fill power of 800 and is constructed with a 10-denier fabric, resulting in it having an excellent warmth-to-weight ratio. The Ghost Whisperer is an extremely popular jacket for ultralight backpackers and thru-hikers and would be an excellent jacket to choose for your ultralight backpacking kit.

Fleeces

When it comes to choosing a fleece for backpacking, I prefer something that is breathable and can be worn while being active. I typically opt for a grid fleece pullover, particularly those made with Polartec® Power Grid® fabric, of which REI offers several options. Grid fleece is ideal for backpacking and hiking due to its excellent warmth-to-weight ratio, breathability, and moisture-wicking properties.

Product Weight (W's / M's) - exact weight varies by size Price
Patagonia R1 Pullover (Women's 🔗 / Men's 🔗) 9.8 oz / 11.7 oz $139

Mountain Hardwear Summit Grid Half-Zip Shirt Men's 🔗 11.5 oz $85
Patagonia R1 Air Full-Zip Hoodie (Women's 🔗 / Men's 🔗) 10.9 oz / 12.9 oz $179

Descriptions of each fleece:

  • Patagonia R1 Pullover (Women's / Men's): Versatile mid-layer with excellent breathability and moisture-wicking properties. Ideal for layering in cool to cold conditions. Polartec® Power Grid™ fabric provides lightweight warmth and durability. This is a very popular fleece amongst ultralight backpackers.

  • Patagonia R1 Air Zip-Neck Pullover (Women's / Men's): Lighter and more breathable version of the R1, with a zip-neck for ventilation. Ideal for high-exertion activities in cooler conditions. Unique zigzag pattern enhances moisture-wicking and drying. This is the only non-grid fleece option I have listed here.

  • Mountain Hardwear Summit Grid Tunic Hoodie Women's: Grid fleece pattern offers a balance of warmth and breathability. This fleece is very similar to the popular Melanzana Micro Grid Hoodie, if you're looking for a similar style fleece. It is made out of Polartec® grid fleece.

  • Mountain Hardwear Summit Grid Half-Zip Shirt Men's: Similar to the previous option, this one is also made out of a grid fleece, but is a men's version and doesn't have a hood.

  • Patagonia R1 Air Full-Zip Hoodie (Women's / Men's): Full-zip, hoodie version of the R1 Air above.

Out of these options, I would choose the Patagonia R1 Pullover (Women's / Men's) because it is a lightweight, versatile layer made of a grid fleece.

Rain Jackets/Shells

When choosing an ultralight rain jacket, look for a lightweight, waterproof, and packable option with features like taped seams, adjustable hood, and ventilation options (such as pit zips) for comfort and protection in wet conditions. I also recommend choosing a rain jacket based on the conditions you will be backpacking in. If you expect heavy rain, investing in a heavier, more durable rain jacket is sensible.

If I had to choose one of the above rain jackets, I would choose the Outdoor Research Helium Rain Jacket (Women's / Men's) because of its weight and price. Not only is it the lightest option, but it is also the most budget-friendly option.

Cooking Gear

The following cooking gear has been my go-to ultralight kit for the past three years. In total, it weighs only 5.6 oz. The essence of ultralight backpacking is to carry only essential gear, and you can significantly reduce weight with a minimal and ultralight cooking gear kit. Personally, I use only a small pot, a single utensil, and a compact stove. I have never brought a mug with me backpacking because the small pot can double as a mug when needed. This is the cooking gear I used for over 6,400 miles of backpacking and I will continue to use in the future:

Descriptions of each option:

  • TOAKS Light Titanium 550ml Pot: Ultra-lightweight titanium construction. I used this pot on all of my thru-hikes. I never need to boil more than approximately one cup of water at a time, so this pot is the perfect size for me. I personally never eat out of it and eat my food out of food bags. This pot does come in larger sizes, too, but I like this size because it helps keep my cook setup very minimal.

  • MSR PocketRocket 2 Stove: Simple and efficient design for quick boiling times. Compact and easy to pack, making it a favorite among minimalist backpackers. I used this stove on all of my thru-hikes. It is very reliable and ultralight.

  • Sea to Summit Frontier Ultralight Long Handle Spork: In the past, I've used the spoon version of this spork, but I really wish I had the spork version so it can double as a fork and spoon. Whether you choose spork or spoon, the important thing is to get the long version. The added length makes eating out of backpacking meal bags 1000x times easier, trust me.

Water Treatment

There are a lot of different options available for treating water to make it safe to drink. The two main options are a filter or a chemical treatment. To further reduce weight, consider avoiding heavy water bottles. You can save a lot of weight by reusing a lightweight plastic water bottle, such as a Smartwater bottle, which can still be reused on multiple backpacking trips. This simple change can significantly reduce your pack's overall weight.

Descriptions of each water treatment option:

  • Aquamira Water Treatment: Chemical treatment that uses chlorine dioxide to kill bacteria, viruses, and cysts in water. Compact and lightweight. When there are no floaties (dead bugs, dirt, etc.) in the water, I typically use Aquamira.

  • Sawyer Squeeze Water Filter System: Versatile and lightweight filter system with a 0.1-micron hollow fiber membrane. Can be used directly on a water bottle, inline with a hydration pack, or with the included squeeze pouch. Effective against bacteria, protozoa, and sediment, with a long lifespan of up to 100,000 gallons. This is a very popular water filter for backpacking and thru-hiking.

  • Sawyer Micro Squeeze Water Filtration System: Compact version of the Sawyer Squeeze, with the same 0.1-micron filtration level. Lightweight and easy to use. Includes a squeeze pouch and can be attached to standard water bottles or hydration packs. This is my personal favorite water filter to use when backpacking because it is smaller and lighter than the standard Sawyer Squeeze.

  • Katadyn BeFree 1.0 L Water Filter Bottle: Integrated water bottle and filter system with a 0.1-micron hollow fiber filter. Collapsible bottle design for easy packing and carrying. Fast flow rate and easy cleaning by simply shaking or swishing the filter in water. This filter has a pretty fast flow rate until you use it in water that has a lot of stuff that needs to be filtered. If you are backpacking somewhere where the water is mostly clear, then this is a good option.

If I had to choose one option out of the above, I would choose the Sawyer Micro Squeeze Water Filtration System because it is lightweight and easy to use with a standard water bottle. This has been my go-to water filter for several years now.
