We’ve rounded up 13 of the best sleeping bags for stomach sleepers on the market, so you can rest easy (literally) no matter where you are.

Here are our top 13 picks for the best sleeping bags for stomach and side sleepers:

1. Hyke & Byke Eolus 0 F Hiking & Backpacking Sleeping Bag – 4 Season mummy side sleeping bag

Looking for a lightweight sleeping bag that will keep you warm and toasty on your next backpacking trip? Then check out the Hyke & Byke Eolus 0 F Hiking & Backpacking Sleeping Bag! This mummy-style side sleeping bag is rated for four seasons, so it’s perfect for use all year round. You will feel as if you are sleeping on a warm cloud!

With an outer and inner nylon shell that has vertical baffles. These baffles allow you to adjust the 800-fill power insulation to suit your temperature needs better.

The stomach mummy sleeping bag is designed for 4 seasonal weather, especially cold weather. It has WR 800 fill power goose down insulation and a ClusterLoft base to keep you warm from 0 – 30 F. The sleeping bag is made from 400T 20 D ripstop nylon fabric and has two large YKK zippers with anti-snag sliders. It is also hydrophobic and water-repellent. The sleeping bag will fit a 6ft 6in person and is ultralight, making it perfect for backpacking and camping.

Pros & Cons

Let’s start with the positive stuff!!

Tested on Mount Kilimanjaro, and let me tell you, those Hyke and Byke Eolus 0-degree ultralight sleeping bags were clutches! It got pretty chilly at night, but we were toasty and warm. I highly recommend this sleeping bag for any demanding hiking adventure travel where the temperatures will drop below freezing. This is one the warmest mummy stomach sleepers you can get.

What some hikers have complained about in this sleeper is:

The top and bottom have different insulation; while the upper side keeps you toasty, the bottom can feel chilly.

2. The TETON Sports LEEF Ultralight Mummy Sleeping Bag:

TETON Sports LEEF Ultralight Mummy Sleeping Bag is a great option for those who want a versatile bag that can be used in various climates. It has a temperature rating of 30 degrees Fahrenheit, making it suitable for use in spring and summer. But it also has a zip-out liner that can be removed for use in warmer weather.

If you’re looking for a mummy sleeping bag that’s roomier than the average, with three different size options, the TETON Sports has you covered with their LEEF sleeping bags. It’s available in three temperature ratings, and it’s affordably priced. We appreciate this bag’s extra space, making it much more comfortable to sleep in. Plus, they’re backed by a lifetime warranty, so you can rest assured that your purchase is protected.

This sleeping bag is perfect for tossing and turning, especially if you’re also a side sleeper. The zipper is very sturdy and easily accessible from the top and bottom. Once you’re inside, you won’t want to come out! The sleeping bag will hold the warmth perfectly well at 32 degrees, but if it’s 20 degrees outside, you should use a sleeping bag liner and put on your thermals.

• Limit: 23 F
• Extreme: 5 F

Dimensions:

This is a winner for Backpacking, Camping, and Hiking, Cold-Weather Sleeping Bag at under $100 and a lifetime warranty.
I recently bought the Teton 0* LEEF “Scout” sleeping bag, and I am very pleased with its performance. It is great for backpacking in potentially wet winter conditions, as it is synthetic and, therefore, won’t become completely useless if it gets wet. It is also very warm – I was toasty warm and dry all night when I tested it in high-20s weather with rain/sleet. The only downside is that the stuff sack it comes with is overkill, as it is very heavy.

7. The Sierra Designs Backcountry Bed 700 Sleeping Bag

The Sierra Designs Backcountry Bed 700 is the bag for hard-to-please campers who want a bag that’s comfortable and easy to use. It has a temperature rating of 30 degrees Fahrenheit and is made with synthetic insulation.

Sierra Designs has come out with a new zipperless mummy bag called the Backcountry Bed. This bag is designed for maximum comfort with its spacious fit and innovative closure flap. However, it sacrifices some weight and thermal efficiency. Nevertheless, many people will be willing to pay the extra price for this unique bag’s luxury.

The Backcountry Bed 700 also has Sierra Designs’ unique zip-together design, which lets you zip two bags together to create a double-wide sleeping surface. And it has an integrated pillow pocket that lets you inflate an included pillow for added comfort.

If you’re tired of being woken up by a zipper in the middle of the night, our backpacking sleeping bag review gives you two choices: the Sierra Designs Backcountry Bed 700 / 35 or Sierra Designs Cloud 20. Both bags have interesting but similar flap-closure designs.

Here are reasons we like the bag.

Warmth:

The Backcountry Bed is a comfortable sleeping bag, thanks partly to its unique design and partly to the relatively thin amount of insulation it packs. With a “blanket” footbox design, you can put your feet out of the bag if desired. The bag also has a large opening, making it easier to get in and out of than the traditional mummy style. The only downside to this is that there is no way to close the bag fully.

There are straps on each side of the bag that allow you to cinch it tight for extra warmth or leave it loose for extra room when not wearing the bag, but even with these tightened, there are gaps between the sides of the bag and your body, that wind and cold could potentially seep through. It’s worth noting that we didn’t experience any cold spots in our testing, even during our most frigid nights at high altitudes like Mount Shasta and Grand Teton National Park. Sierra Designs does sell a separate insulated comforter for added warmth in colder conditions.

Packed Size

The Backcountry Bed did very well in our packed size testing compared with other bags we tested. We measured its packed size at 12.5L, which is significantly smaller than some competing “mummy” style bags but still larger than some of its competitor “quilt” style bags (the lightest weight quilt-style bag we tested was just under 10L). When packed with a dry-bag backpacking seals

Our Verdict: 

This sleeping bag is heavy and not even that warm. This is because of all the extra materials needed for the luxurious comforter closure.

8. The Kelty Cosmic Down 20 Sleeping Bag

Who says being a gearhead can’t be stylish? The latest trapezoidal baffle construction is thermally efficient, lightweight, and warm. The 550 fill down is environmental and health-friendly, while the buttery-soft 20D Nylon shell fabric is durable.

The zippered internal stash pocket is perfect for headlamps, cell phones, or actual stashes. The zipper draft tube with anti-snag zipper design makes it easy to get in and out, and the dual slider for ventilation with locking zippers is a nice touch. The natural fit spacious foot box means more room to wiggle your toes, and it comes with a stuff sack for quick departures.

Looking for a cozy and comfortable sleeping bag to keep you warm on your next camping trip? Look no further than the ISO-Rated Sleeping Bag! This sleeping bag is available in three different sizes to fit just about anyone and comes with an extreme temperature rating of -11°/-24°C.

9. The Mountain Hardwear Lamina Z Spark 34 Sleeping Bag

The Mountain Hardwear Lamina Z Spark 34 is another great option for those who want a versatile bag that can be used in various climates. It has a temperature rating of 30 degrees Fahrenheit, making it suitable for use in spring and summer. But it also has a zip-out liner that can be removed for use in warmer weather.

We’ve all been there. You’re lying in your sleeping bag, trying to get comfortable and warm, but you just can’t seem to get there. You toss and turn and adjust your position a million times, but it’s not working. But with the new reflective elements in welded Lamina™ construction, you can finally rest easy.

The thermal Q insulation (80% recycled material) will keep you warm and dry, while the shaped protective collar prevents warm air from escaping. The contoured foot box follows your natural foot position for maximum warmth and comfort, and the perfect fit hood keeps out drafts and traps in warmth.

The 30D ripstop nylon material is lightweight and very compressible, with a DWR coating to repel water. Plus, the No. 5 2-way zipper with an anti-snag system makes it easy to slip in and out, and the reflector zipper makes you visible at night. So finally, you can get a good night’s sleep – even when you’re camping.

10. The Coleman Brazos Cool-Weather Sleeping Bag

The Coleman Brazos is a great option for anyone on a tight budget. It’s durable, warmer than some of the more expensive bags, and perfect for anyone looking for a simple bag that will just get the job done.

The Brazos also has a draft tube that runs along the zipper to prevent heat escaping. And it has a quilted design that prevents the insulation from shifting, so you’ll stay cool all night long.

Weighing in at 4.1 pounds, the Slumberjack Country Squire 0° sleeping bag is a great option for budget-minded campers looking for a warm bag. It’s made with a polyester shell, a Tricot knit liner and is filled with Coletherm synthetic polyester. This cold weather sleeping bags for side sleepers has a rectangular shape and is only available in one length, but it does have some useful features, like a draft collar and an internal storage pocket. The only downside to this sleeping bag is that the liner could be improved.

Our Verdict:

We were surprised by how well the Brazos performed our warmth and ice tests. It did better than more expensive bags, and we were impressed by its insulating ability.

11. The Sea to Summit Ember EB I Sleeping Bag

The Sea to Summit Ember Quilt is a great option if you’re looking for a unique backpacking quilt with extra versatility. This quilt review covers all the features that make this quilt stand out from other quilts on the market.

The sleeping bag for stomach sleepers Quilt is available in three models: Ember I, Ember II, and Ember III. The Ember I is rated at 40 degrees, the Ember II is rated at 30 degrees, and the Ember III is rated at 20 degrees. The Sea to Summit Ember Quilt performed down to its stated temperature rating, which didn’t surprise me as their products are typically true to their ratings.

The Ember EB I is also designed with Sea to Summit’s Thermoloft insulation, which traps heat even when wet. And it has an integrated pillow pocket that lets you inflate an included pillow for added comfort.

The Mummy bag is packed with 850+ fill treated down, meaning it’s super light and won’t absorb water. They’re also RDS certified, ethically sourced, and come with a certificate of the responsibly sourced down. So you can rest assured knowing you’re getting a high-quality product.

This quilt has a total weight of 27 ounces and is filled with 17.5 ounces of 850+ DownTech down. The shell material is made from 10D nylon and the liner material is made from 7D nylon. The quilt has a minimum temperature rating of 14-25° F and a compressed volume of 5.4L.

This quilt has a total weight of 27 ounces and is filled with 17.5 ounces of 850+ DownTech down. The shell material is made from 10D nylon, and the liner material is made from 7D nylon. The quilt has a minimum temperature rating of 14-25° F and a compressed volume of 5.4L.

Our Verdict:

The Sea to Summit Ember Quilt has only been around for a few short years, but it has already made several improvements. These include increasing the down loft to 850+ fill UltraDry down, reducing the denier weight of the fabric to 7D inner and 10D outer fabrics, increasing the shoulder room, improving the foot box closures, and using a new PFC free DWR finish.

In 2022, the QuiltLock system will be added to allow the Ember Quilt to attach to any and all of the Sea to Summit Sleeping bag range. Over the years, there has been a continuous improvement in the Ember Quilt from Sea to Summit.

12. The REI Co-op Magma Trail Quilt Sleeping Bag

The Magma 30 is a great quilt for those looking for a warm, no-frills option. The continuous baffle design keeps the down lofty and the pad strap system and draft tube around the neck area keep warm air sealed in. The quilt has a 30F rating, but we felt that it is slightly conservative and comfort in lower temps is possible.

The REI Co-op Magma Trail Quilt is a great option for those who want a versatile bag that can be used in a variety of climates. It has a temperature rating of 30 degrees Fahrenheit, making it suitable for use in spring and summer. But it also has a zip-out liner that can be removed for use in warmer weather.

The REI Co-op Trail Magma Quilt 30 is a simple and functional piece of gear made of quality materials that will keep you warm and comfy while sleeping off those mileage days on the trail. However, its main disadvantage when comparing other quilts in its category is its footbox. Although quite warm and roomy in of itself, it’s not possible to transform the quilt into a full-on blanket for warm nights and campsite hangouts, making the quilt a little less versatile piece of kit than could be possible.

Specs:

• Temperature Rating (F) : 30 degrees (F)
• Weight : Short: 1 lb. 1.5 oz. Regular: 1 lb. 3 oz.  Long: 1 lb. 4 oz.
• Shell      Pertex ripstop nylon
• Stuff Sack Size:
• Short: 13 x 4.75 inches
• Regular: 13 x 4.75 inches
• Long: 13 x 4.75 inches
• Gender: Unisex
• Fits up to: 72″
• Shoulder / Hip/ Footbox Girth:  56″ / 52″ / 44″

The REI Magma Trail Quilt 30 is a cozy little number that’ll keep you toasty all night long. It’s got a nifty pad attachment system that keeps it in place, and it’s perfect for keeping those pesky drafts at bay. So snuggle up tight and enjoy a good night’s sleep!

Our Verdict:

If you’re considering switching from a sleeping bag to a quilt, there are a few things you should know. For one, quilts require a bit of practice and adjustment to get used to. Unlike sleeping bags, which are pretty much idiot-proof. Also, the REI Magma Trail 30 Quilt has three positions where you can attach the sleeping pad cords: the two shown above and or at the top of the quilt, just below the collar. The collar closes with a snap in the back, which pulls the sides of the quilt together, so you don’t need a cord there. But it’s something you may want to experiment with. So, if you’re thinking of making the switch to a quilt, do yourself a favor and take it on a shakedown test trip close to home before you bet the farm on it.

13. The Western Mountaineering UltraLite Sleeping Bag

The UltraLite sleeping bag is one of the toughest on the market and can be used in any season. It is filled with 17 oz of premium 850+ FP down and has a continuous horizontal baffle design that allows you to move the feathers to the underside of the bag to vent excess heat on warmer nights. Although it is one of the more expensive sleeping bags, it is worth the investment for experienced backcountry travelers.

The UltraLite also has an internal pocket that’s perfect for storing your phone or other small items. And it has an integrated pillow pocket that lets you inflate an included pillow for added comfort.

Our Verdict:

If you’re willing to spend upwards of $400-$500, we think a bag is a better investment than a quilt. The UltraLite classifies as ultralight, but diehard gram counters might disagree. The Western Mountaineering SummerLite is fully-featured and rated to 32 degrees, coming in at just 19 ounces.

If you’re looking for a light, warm, and compressible bag, the Western Mountaineering UltraLite is a great option. It uses 850 fill-power down for insulation, which results in a high loft and a great warmth-to-weight ratio. The UltraLite also has decent compressibility and surprising durability given its weight.

No matter what your needs are, there’s sure to be a sleeping bag on this list that’s perfect for you. So next time you’re planning a camping trip, make sure to bring along one of these bags – your back (and your stomach) will thank you!
