What you should look for
(and what we test for)
Fit and Comfort
Ensure a good fit and comfort, as the sleeping bag should be snug without being tight, and having a bag that's too large can leave cold spots where your body heat can't reach.
Consider the temperature rating of the ultralight sleeping bag - it should keep you cozy in the coldest temperatures you expect to encounter on your adventure, so check the bag's lower limit rating (for men) or comfort rating (for women).
Weight and Packability
Carefully evaluate the bag's weight and packability, with lighter and more compressible options making your backpack less cumbersome and your hikes easier – but remember, sometimes a couple of extra ounces can make the difference between shivering or sleeping soundly at night.
Materials and Durability
Look into the materials used for the bag, as high-quality, tear-resistant fabrics will withstand rough handling and last longer, and down insulation usually offers a better warmth-to-weight ratio but won't perform well if it gets wet.

The Feathered Friends Hummingbird UL 30 is a top pick for outdoor enthusiasts on the hunt for a high-quality, ultralight sleeping bag. This bag rips off the tags on the niche of lightweight backpacking gear while also boasting awesome warmth and comfort features.
Built with a 950+ fill power goose down, this bag kicks up some serious heat and gives the Hummingbird its ultra cozy feel. It manages to do this without tipping the scales too much - the bag weighs in at a mere 1.42 lbs, which is piddly compared to many other sleeping bags on the market perfect for those keen on backpacking or climbing.
Its Pertex fabric shell provides some real chops when it comes to durability. Users have pointed out that despite its light weight, this sleeping bag withstands some pretty rough treatment without showing any signs of wear and tear.

Any chinks in the armor? Well, some users have grumbled about its narrow design especially around the feet. If you're a restless sleeper or someone who likes to stretch it out in their bag, this could be a snugger fit than you'd like. It’s not necessarily a deal breaker, however some users find it a little discomforting.
Another tiny gripe is with its price tag. The Hummingbird is pricier than many other options on the market.

Western Mountaineering SummerLite$485.00
Based on our research and testing, we think the Western Mountaineering SummerLite is a great choice if you're looking for a ultralight sleeping bag to go play hard outside with, if our top pick isn't quite what you're looking for.
Reasons to Buy
- Perfect for three-season camping
- Great for backpacking due to lightweight nature
- Warm enough for most but not excessively hot
- Solid construction and durability
Reasons to Avoid
- Not designed for extreme cold weather
- May be too narrow for those who prefer more room
- Quite pricy compared to other models
First and foremost, the Western Mountaineering SummerLite is an awesome featherweight friend for your summer adventures. I mean, the best surprise about this bag isn't just its lightness, but its extraordinary warmth-to-weight ratio. It weighs just a hair over a pound (which is lighter than your favorite water bottle, by the way), but it's cozy enough for temperatures down to 32 degrees F.
According to folks who've tested this bag, they rave about its comfort. No tight, claustrophobic mummy design here; the SummerLite gives you wiggle room where you need it. It seems pretty clear that the fine folks at Western Mountaineering have paid attention to what hikers and campers want from their sleeping bag.
The SummerLite is stuffed with 850-fill goose down, which is nature's top insulator, curling you up in its plush warmth. It's also well-known for packing down small, which is a big plus if you're one of those bare-bones backpackers trying to keep space at a premium.
So, water-resistance - it isn't the SummerLite's strongest suit, as reported by some wearers, especially in comparison to synthetic bags. But, hey, if you're roughing-it right, your sleeping bag shouldn't be getting soaking wet anyway. Just be sure to avoid pitching your tent in a puddle and you’ll be good to go.
The general consensus among users also applauds the bag's full-length zipper. This gives you the option of unzipping the bag entirely and using it like a quilt on more tepid nights. A nice touch, wouldn’t you say?
One aspect that some folks point out is the price. Yes, it's a bit steep for a sleeping bag. But users consistently came back to the same thought: you are getting what you're paying for. The SummerLite is a top-quality bag that can last upwards of a decade with proper care.
As for the aesthetics, the SummerLite sports a minimalist design with that pop of color we all love. The bright yellow is the definition of cheerful and makes the bag fairly easy to spot among your other gear.
Katabatic Gear Palisade 30$395.00
Based on our research and testing, we think the Katabatic Gear Palisade 30 is a great choice if you're looking for a ultralight sleeping bag to go play hard outside with, if our top pick isn't quite what you're looking for.
Reasons to Buy
- Superior warmth-to-weight ratio
- Impressive compressibility and packability
- Highly durable
- Versatile, adjustable sleeping system
Reasons to Avoid
- Not the cheapest option
- Foot box might be too narrow for some
- Might feel a bit less comfortable for side sleepers
The Katabatic Gear Palisade 30 caught our eye not just for its ultralight properties, but also its compact design and impressive warmth-to-weight ratio. It weighs in at a minuscule 16.85 ounces, making it a standout choice for those looking to shave weight on multi-day hiking or climbing trips.
This sleeping bag blends 900 fill power goose down insulation with Pertex Quantum fabric. Together, these ensure impressive heating capabilities, while remaining resistant to moisture. It thrives in temperatures as low as 30 Fahrenheit, but through customer feedback, we've found it performs better in slightly warmer environments.
The design has been largely praised by users for its versatile flexibility. The hood-less, quilt style and pad attachment system allow for changes in sleep position and temperature regulation without compromising the user's warmth. Pioneering this innovative style, Katabatic Gear has nailed it with the Palisade 30.
Though it comes with a higher price tag, customers have reported the exceptional durability and build quality justifies the investment. Not a common complaint, but a few users have mentioned the footbox area could offer more room. Others have also mentioned the lack of a full-length zipper restricts their ability to use it as a quilt.
Beyond the minor foot space issue, the packability of this sleeping bag is consistent with its ultralight status. Folded and stored properly, it uses precious little pack real estate, a factor that backpackers have given a thumbs up.
Satisfied customers cite comfort and loft retention among this bag's strengths. It has 6-inch vertical baffles which help maintain its shape and presentation over numerous adventures.
Also, customer care of the manufacturing company received an honorable mention by happy campers, indicating a positive after-sale experience. It's reassuring for those considering taking the plunge on this big-ticket item.
In essence, the Katabatic Gear Palisade 30 provides a high-performance sleeping experience for serious outdoor enthusiasts. However, due to its budget-stretching price, this bag is best suited for those who demand optimum performance and are willing to pay for it.
REI Co-op Magma 30
Best Budget Ultralight Sleeping Bag

If you're on a budget but don't want to compromise on quality, the REI Co-op Magma 30 is certainly worth considering. This sleeping bag has plenty of features to shout about. For a start, it's ultra-lightweight, tipping the scales at just 1 lb. 7.4 oz. For backpackers who count every single ounce, this could be a game-changer.
The sleeping bag also boasts of a temperature rating of 30 degrees Fahrenheit, which should keep you warm in most three-season camping scenarios. This rating may be a tad optimistic if we consider some user feedback. So, if you're someone prone to feeling cold or will be camping in frosty conditions, an extra thermal liner might be an added safety layer.
Customer reviews highlight the excellent construction quality of the Magma 30. This sleeping bag is packed with 850-fill-power goose down, providing lofty warmth that's well distributed throughout. The down is also responsibly sourced, an essential point for eco-conscious campers.
Users love the bag's water-resistance too. The down is treated with a durable water repellent (DWR) finish, which helps to ensure you stay dry, even if things get a little dewy overnight. A watertight stuff sack is included, protecting the bag during transportation. Nonetheless, some users suggested it could be more robust.
The Magma 30 is praised for its comfort. Implicit in the design is a warmth-to-weight ratio that provides at-home snugness, without the excessive bulk. The sleeping bag's contoured hood and spacious footbox further enhance the optimal sleeping conditions. However, some reviews have flagged that larger folks may feel a little restricted.
The bag's anti-snag zipper is a detailed highlight appreciated by users, who commented favorably about its smooth operation and minimal fuss. However, a few noted that the bag might benefit from a small internal pocket for essentials like a phone or flashlight.
Perhaps one of the resounding verdicts from the users is that the REI Co-op Magma 30 offers remarkable value for money. Given its feature set and overall quality, it's a cost-effective solution for backpackers watching the scales and the wallet!

Reasons to Buy
- Excellent insulation

- Delivers a cozy sleeping experience
