To help you find the perfect sleeping bag for your next adventure, we’ll cover the best sleeping bag brands on the market.
Best Sleeping Bag Brands List
- Western Mountaineering
- Sea to Summit
- Mountain Hardwear
The above are all good sleeping bag brands and any of their bags will be good quality. And here are the individual review.
Western Mountaineering has become one of the most famous outdoor brands in the lightweight backpacking industry. The company has been around for over 30 years.
Down-filled garments and sleeping bags are the main product lines of the brand. Almost all Western Mountaineering sleeping bags use 850+ fill power down.
Moreover, the brand only uses high-quality goose down. All Western Mountaineering down sleeping bags are 100% RDS certified. The RDS label guarantees that the down in your sleeping sack has been ethically sourced.
Most of the brand’s sleeping bags have a semi-rectangular or mummy bag shape. To ensure the highest possible quality, the brand still makes its sleeping bags in the USA. All of the brand’s sleeping bags come with a lifetime warranty against defects in materials and workmanship.
My Pick: Western Mountaineering UltraLite
- Total weight: 28.9 oz
- Fill weight: 16 oz
- Fill power: 850+
- Iso comfort rating: 25°F
- Lifetime warranty
As an avid backpacker and outdoor enthusiast, I’ve always prioritized lightweight and compact gear. After recently spending several nights in the Western Mountaineering UltraLite down sleeping bag, I can confidently say it has exceeded my expectations in terms of warmth, comfort, and packability. Here’s a detailed breakdown of my experience with this top-notch backpacking sleeping bag.
Warmth & Temperature Rating
The UltraLite down sleeping bag is rated for temperatures as low as 20°F (-6°C), and I found this to be quite accurate. During my recent trip in the Sierra Nevada mountains, nighttime temperatures dropped to around 25°F (-4°C), and I stayed warm and cozy throughout the night. The 850+ fill power goose-down insulation provides excellent loft and heat retention, making this a warm sleeping bag suitable for cold weather and one of the best in its weight class.
Weight & Packability
Weighing in at just 1 lb 13 oz (820 g) for the regular size, the UltraLite down sleeping bag is a dream come true for ultralight backpackers. When compressed in the provided stuff sack, the mummy bag packs down to a surprisingly small size, leaving ample room in my pack for other essentials. This makes it an ideal choice for long-distance hikes or minimalist adventures.
Comfort & Fit
The UltraLite down sleeping bag features a mummy bag shape, which helps to maximize thermal efficiency without sacrificing comfort. The sleeping bag is designed with a full-length zipper and a draft collar to prevent cold air from sneaking in. I found the 5-inch loft to be incredibly comfortable, and the continuous baffles allowed me to adjust the down distribution to suit my sleeping preferences easily.
Materials & Durability
Western Mountaineering is known for its high-quality materials and construction, and the UltraLite mummy bag is no exception. The outer shell is made from a lightweight, water-resistant, breathable fabric that feels soft. The bag’s stitching and construction are impeccable, and I have no doubts that it will stand up to years of use in the great outdoors.
Price & Value
The Western Mountaineering UltraLite sleeping bag comes with a higher price tag compared to some other sleeping bags on the market. They don’t make synthetic sleeping bags. Only the best down is used. However, considering the excellent warmth-to-weight ratio, top-quality materials, and overall performance, I believe it’s a worthwhile investment for serious backpackers seeking a reliable and comfortable sleeping solution for their adventures.
The UltraLite is one of the warmest 3-season sleeping bags on the market, so not so great as a summer sleeping bag. It’s a great choice for mid to high-elevation environments as well as shoulder seasons.
To help with ventilation in the summer, the UltraLite features a two-way zipper. It also includes a cozy draft collar that helps seal out the cold.
The sleeping bag has continuous horizontal baffles. This means that you can put it underneath you if you want less warmth or on top of you for more warmth. If you think this model might be too warm for you, check out the MegaLite.
High-quality tents, backpacks, outdoor clothing, and sleeping bags have been Marmot’s main product lines since 1974. As well as being one of the best sleeping bag brands, Marmot is one of the go-to brands when it comes to lightweight backpacking. It was one of the very first brands to use Gore-Tex in its products.
Thanks to Marmot’s proprietary materials and innovative technology, the brand’s sleeping bags are considered to be very reliable. With proper care, Marmot gear can last for decades.
Aside from high-quality down, the brand uses a proprietary synthetic insulation material called the Eco Featherless. Compared to most outdoor brands, Marmot goes to greater lengths to ensure its means of sourcing and production are sustainable and environmentally friendly.
Our Pick: Marmot Phase 20
- Total weight: 23.3 oz
- Fill weight: 14.1 oz
- Fill power: 850+
- Iso comfort rating: 30°F
- Very warm
- Adjustable hood
- The zipper is small
As an avid outdoor enthusiast and experienced camper, I have tried a variety of backpacking sleeping bags over the years. The Marmot Phase 20 sleeping bag is one of the most impressive I’ve used, and I’m excited to share my experience with you.
Warmth and Insulation
The Marmot Phase 20 is rated for temperatures down to 20°F (-7°C), making it an ideal 3-season sleeping bag. The 850-fill-power goose down insulation provides impressive warmth-to-weight ratio. Marmot’s Down Defender treatment ensures the sleeping bag down stays dry and lofty, even in damp conditions. I found the bag to be incredibly warm and comfortable during chilly nights in the mountains, without any cold spots or drafts.
Weight and Packability
Weighing in at just 1 pound 7.3 ounces (656 grams), the Phase 20 is one of the lightest sleeping bags in its class. This is a fantastic feature for backpackers looking to shed weight without sacrificing warmth. The included compression sack allows the bag to pack down to a compact size, making it easy to fit in a backpack without taking up much space.
Comfort and Fit
The Phase 20’s anatomically designed footbox and 3D hood provide excellent comfort and warmth retention, so you don’t need to wear a warm hat to get a good night’s sleep. The smooth-curved baffles and anti-snag slider on the full-length YKK zipper make getting in and out of the bag a breeze. The bag’s mummy shape offers ample room in the shoulders and tapers down toward the feet, providing a snug and cozy fit without feeling too restrictive.
Material and Durability
The sleeping bag features a 10-denier Pertex Quantum shell, which is both lightweight and durable. The shell is water-resistant and windproof, ensuring you stay protected in various weather conditions. The high-quality materials and construction give me confidence that the Phase 20 will withstand the test of time.
The Marmot Phase 20 comes with a premium price tag, but I believe the investment is worth it. The combination of lightweight materials, warmth, and packability make it a fantastic choice for backpackers and campers who value performance and comfort.
Compared to other sleeping bags that weigh the same, the Phase 20 packs down really small.
It may seem a bit unusual, but one of the biggest retail chains in the US is also one of the best sleeping bag brands. REI makes and designs some of the best camping and hiking gear on the market, and the brand’s sacks are no exception.
The gear that REI manufactures varies greatly in both quality and price. The brand’s higher-end quilts and sleeping bags are often praised by experienced backpackers and hikers.
Our Top Pick: REI Co-op Magma 30
- Cozy fabric
- Quality down
- The down is not hydrophobic
I’ve tried various sleeping bags in search of the perfect blend of warmth, weight, and packability. After spending several nights in the REI Co-op Magma 30 sleeping bag, I’m delighted to say that it checks all these boxes and more.
Warmth and Comfort
The Magma 30 boasts an impressive warmth-to-weight ratio with its 850-fill-power goose down insulation. I found it to be extremely cozy in temperatures as low as 35°F, while still being breathable enough for warmer nights. The bag’s draft collar and cinchable hood kept drafts at bay, and the trapezoidal footbox provided ample room for my feet to stay warm and comfortable. The 15D Pertex Quantum shell and lining not only feel soft against the skin, but they’re also water-resistant and durable, ensuring a dry and pleasant experience even in damp conditions.
Weight and Packability
One of the Magma 30’s sleeping bag shining features is its weight. Tipping the scales at a mere 1 lb. 7.2 oz. for the regular size, it’s a lightweight champion in its class, making it an ideal companion for long treks and multi-day adventures. The included compression sack allows the sleeping bag to be packed down to an impressively small size (approximately 7″ x 14″), freeing up valuable space in my backpack for other essentials.
Fit and Sizing
The Magma 30 comes in three sizes: regular (up to 6′), long (up to 6′ 6″), and women’s (up to 5′ 6″). I opted for the long version, and at 6′ 2″, I found the fit to be spot-on, with enough room to move around without feeling constricted. The women’s version features additional insulation, making it even more suitable for those who tend to sleep cold.
Priced at $329 for the regular size, the Magma 30 isn’t the cheapest sleeping bag on the market, but it delivers outstanding value for its high-quality materials, warmth, and ultralight design. If you’re a serious backpacker looking for a reliable and cozy sleeping bag that won’t weigh you down, the Magma 30 is well worth the investment.
This outdoor gear company became famous when it invented the self-inflating sleeping pad way back in the ’70s. Therm-a-Rest’s innovative approach to camping and backpacking gear gave the competition a run for its money.
Today, most hikers and backpackers love Therm-a-Rest for its super comfortable hammocks, camping pillows, backpacking quilts, as well as sleeping bags. NeoAir pads are arguably the brand’s best-selling product line.
In terms of technical performance and warmth-to-weight ratio, Therm-a-Rest’s Fast & Light sleeping bags outperform most of the competition. Like most other high-quality outdoor sleeping bag brands, Therm-a-Rest only uses RDS certified down.
The brand’s sleeping bags feature patented elastic straps known as SynergyLink connections. They allow you to easily and securely attach your sack to your sleeping pad.
Our Top Pick: Therm-a-Rest Hyperion 20
- Total weight: 20.4 oz
- Fill weight: 12.7 oz
- Fill power: 900
- Iso comfort rating: 20°F
- 900 fill hydrophobic down
- Impressive warmth to weight ratio
- The zipper runs half-length only
I’m always on the lookout for gear that is lightweight, compact, and reliable. Therm-a-Rest’s Hyperion 20 sleeping bag recently caught my attention, and after putting it to the test, I’m happy to share my thoughts on this ultralight and comfortable sleeping bag.
Warmth and Comfort
The Hyperion 20 boasts a temperature rating of 20°F (-6°C), making it suitable for three-season use. The 900-fill power goose down insulation, with its incredible warmth-to-weight ratio, kept me toasty during chilly nights. The bag’s zoned insulation design strategically places 70% of the down on the top side, which helps retain body heat without compromising weight or packability. The ThermaCapture Lining further enhances the warmth by reflecting radiant heat back to the user. However, for those planning on venturing into colder temperatures, a liner or a warmer sleeping bag might be necessary.
Weight and Packability
Weighing in at just over 1 pound (16 oz / 454 g for the regular size), the Hyperion 20 is incredibly lightweight, making it an excellent choice for ultralight backpacking enthusiasts. The included compression sack allows the bag to pack down to a compact size (roughly the size of a small melon), saving precious space in your backpack.
Fit and Features
The mummy-shaped design of the Hyperion 20 helps conserve warmth by reducing dead air space. The bag comes in three sizes (small, regular, and long), catering to various heights, ensuring a snug fit for most users. The SynergyLink Connectors, a unique feature of the Hyperion 20, allow you to secure the sleeping bag to your sleeping pad, preventing you from sliding off during the night. I found this to be especially helpful on uneven terrain. The bag also features a draft collar, a full-length zipper, and a drawstring hood, which help seal in warmth and allow for easy temperature regulation.
Durability and Materials
The Hyperion 20 features a 10D ripstop nylon shell and lining, which makes the bag lightweight yet durable. The water-resistant Nikwax Hydrophobic sleeping bag down treatment adds another layer of protection in damp conditions, although it’s worth noting that the bag is not fully waterproof. The materials have held up well during my adventures, but as with any ultralight gear, proper care and handling are essential for longevity.
Overall, the Therm-a-Rest Hyperion 20 sleeping bag is an excellent choice for backpackers seeking an ultralight, packable, and warm sleeping bag for three-season use. With its impressive warmth-to-weight ratio, compact size, and innovative features, the Hyperion 20 is a great choice. Just be mindful of its limitations in colder conditions, and treat it with care to ensure it lasts for many trips to come.

Nemo is all about making creative and thoughtfully designed outdoor gear. The brand’s sleeping bags often feature creative and experimental twists that you won’t see anywhere else.
For example, “thermo gills” is a trademark of the brand. Essentially, these “gills” are two zippered vents that allow you to easily regulate warmth. Many of Nemo sleeping bags also come with a “blanket fold.”
Nemo Riff and Jam sleeping bags are also particularly innovative. They are unique mummy bags that are designed for side sleepers who feel too cramped when sleeping in regular mummy bags.

One of the standout features of the Riff 30 is its Thermo Gills. These zippered vents on the top of the bag allow for easy temperature regulation by letting out warm air without exposing you to drafts. This feature is particularly useful for those who tend to sleep hot or during warmer nights.
The bag also includes a full-length YKK zipper, which allows for easy entry and exit. Additionally, the built-in draft collar and draft tube prevent cold air from seeping in, maintaining the warmth inside the bag.

If you are a side sleeper, the Riff 30 is undoubtedly one of the best sleeping bags you can go for.

Well, that is my list of the best sleeping bag brands. Here are some other interesting posts. Get tips on cleaning your sleeping bag or have a read of my review of synthetic sleeping bags vs down.
I love hiking, backpacking, and camping. From the Camino de Santiago to the West Highland Way in Scotland or simply a great day hike on the weekend. Hiking refreshes me, my mind, and keeps my body reasonably fit. So far I have walked three Camino routes and many other long distance hikes in the UK, Canada, and around the rest of Europe. One of the best was my hike up Ben Nevis.
