The 7 Best Sleeping Bags of 2024, Tested and Reviewed

Durable, comfy, and incredibly packable, this unisex sleeping bag checks the boxes for all types of camping. The mummy-style shape allows it to efficiently trap heat, as shown by a 10-20 degree Fahrenheit temperature rating and relatively low weight of 2.2-2.8 pounds (depending on size). While this design is often geared toward backpackers, car campers will appreciate the comfort and insulation it provides when temperatures drop. 

The Nemo Coda Genderless Endless Promise Down Mummy Sleeping Bag comes in three sizes: short, regular, and long, effectively accommodating all heights up to six feet six inches. The bag did a great job of keeping us warm on cool fall nights. Anytime we felt like we were getting too warm, we could quickly unzip the footbox or the half-length entry to increase air flow and cool off. We appreciate how tightly the bag can fit around the head to trap out the cold and ensure swaddled comfort. We were also impressed with how compact the sleeping bag packs in the stuff sack despite how fluffy the down is. Though it retails at a higher pricepoint, we think that the quality materials, packability, and incredible amount of warmth are worth the investment. 

The Details: 12 x 7 inches (regular) packed | 72 inches (regular) long | 2.4 pounds (regular) | Recycled polyester ripstop, recycled polyester taffeta, and 800-fill hydrophobic down | 10 degrees Fahrenheit temperature rating

Keeping warm in cooler spring and fall weather is where the Guide Gear Sleeping Bag excels. We found the flannel interior to be soft, comfortable, and warm while camping in temperatures around 40 degrees Fahrenheit. We also appreciate that the spacious interior can accommodate various body sizes and sleeping positions without feeling constricted. Weighing nearly 13 pounds, the bag felt like a weighted blanket and was able to keep us warm in temperatures below freezing. However, it proved too warm for us when nighttime temperatures were in the mid 60s, since the sole ventilation in this no-frills sleeping bag is the two-way zipper. It doesn’t come with a carry bag: to pack up, simply roll it up and secure the three straps.

The Marmot Lost Coast 40-degree Sleeping Bag is an affordable unisex sleeping bag that doesn’t skimp on durability or functionality. We found the bag to be well made, comfortable, and easy to use. Some of the main selling points include the sturdy zipper that didn’t snag once during testing and the 600-fill down for its insulated warmth.

The mummy-style bag includes a draft collar for a snug fit, yet there was still enough room to sleep on our side and rotate. We found the sleeping bag very breathable, and there were only a few occasions when we unzipped it a bit to adjust the internal temperature. There’s an internal stash pocket that’s handy for stowing a phone or headlamp. We also appreciate that it comes with both a stuff sack and a more spacious bag to store it uncompressed between trips, which is key to extending the sleeping bag’s longevity. 

The Details: 11.8 x 6.3 inches packed | 72 inches long | 2 pounds | Recycled polyester and 600-fill down | 40 degrees Fahrenheit temperature rating

The Marmot Sawtooth Sleeping Bag 15F Down delivers excellent warmth and comfort for camping farther afield. The 15-degree Fahrenheit temperature rating makes it a great pick for camping at higher elevations or backpacking in early spring or late fall. We were pleased with how easy it is to unpack and repack in the stuff sack. Once out of the bag, a quick shake fluffed up the down, which was a dream to sleep on. We hardly noticed our sleeping pad underneath with the cloud-like cushion the down provided.

While camping in more temperate weather, it was a breeze to regulate the internal temperature by unzipping both sides or the vents at the foot area. The dual zippers are an ingenious feature, allowing precise ventilation and the ability to free your arms while keeping the sleeping bag otherwise zipped tight. A drawstring cinch cord further enhances the insulation of the mummy-style men’s sleeping bag. For a comparable women’s sleeping bag from Marmot, try the Teton 15F. 

The Details: 7.5 x 16.1 inches (regular) packed | 72 inches (regular) long | 2.9 pounds (regular) | 20-denier recycled ripstop nylon and 650-fill-power duck down | 15 degrees Fahrenheit temperature rating

The Sea to Summit Spark Down Sleeping Bag for women and men features puffy cushioning and feels very warm wherever you go. While the nylon exterior is thin and light, there is tons of down insulation that had us feeling like we were sleeping with a duvet. The mummy-style design fits close to the body to maximize the warmth of this lightweight sleeping bag, which clocks in under two pounds for the regular and long sizes. That light weight is perfect for backpackers and our tester was able to hike with it for three days throughout Wyoming without feeling weighed down.

We found the adjustable hood spacious enough to fit a camping pillow and keep it in place through the night. There’s also a draft collar for trapping out the cold. Even with the plush down insulation, the bag packs down to a compact size that’s ideal for backpacking or stowing in a carry-on bag. Though pricey, we think that frequent campers will get plenty of value (and many years of adventure) out of this investment. 

The Details: 16 x 13 x 9 inches (regular) packed | 73 inches (regular) long | 1.6 pounds (regular) | 10D nylon, DWR treatment, and 850-fill Ultra Dry Down (RDS-certified) | 15 degrees Fahrenheit temperature rating

The Coleman Flatlands Fleece 30-degree Fahrenheit Double Sleeping Bag is a true two-in-one deal. The unisex double sleeping bag can be zipped apart to have two single sleeping bags, making it a versatile and budget-friendly addition to your camping gear. We found the bag’s fleece lining to be very cozy and comfortable. However, it adds a good deal of weight (the double bag is nearly 12 pounds) compared to down fill. Though we found the rectangular shape gave us plenty of legroom and space for pillows, the extra room hinders insulation, so we are hesitant to push the limits of the temperature rating on a camping trip.  We found the oversized zippers easy to use — they didn’t catch or snag once during testing. We appreciate that the double bag is machine washable, especially with the light blue exterior color that’s prone to showing dirt. 

The Details: 20 x 13 x 12.5 inches packed | 81 x 66 inches expanded | 11.8 pounds | Polyester, Fleece, and Ecotherm fill | 30 degrees Fahrenheit temperature rating

The Big Agnes Sidewinder SL 20 Sleeping Bag for men and women is an incredibly comfortable option that’s well worth the investment for side sleepers. Big Agnes calls itself ‘the Mother of Comfort,’ and we feel that the Sidewinder lives up to the claim. The extra insulation at the hips and feet enhanced our comfort and support while lying on our sides, making it a joy to sleep in. The contoured sleeping bag even moved with us seamlessly as we shifted from side to side. The materials felt rugged and of excellent quality that will last for years. We appreciate that it unpacks and packs into the stuff sack with minimal effort. 

The Details: 8 x 17.5 inches packed | 72 inches (regular) long | 2.3 pounds (regular) | Ripstop nylon, polyester taffeta, and 650-fill-power DownTek/FireLine ECO | 20 degrees Fahrenheit temperature rating
