Best 0 Degree Sleeping Bags of 2024

BEST WINTER BACKPACKING SLEEPING BAG

The Western Mountaineering Kodiak MF is a four season sleeping bag that was designed for backpackers who want to brave extreme conditions in comfort. 

While there are plenty of excellent winter sleeping bags out there, the Kodiak MF is our top choice because it is seriously warm and comfortable. While other bags are equally as toasty, they have a narrower fit that makes them constricting. When it is cold out, we tend to spend more time inside our bags and appreciate the extra room. The Kodiak MF adds a few inches in the shoulders and is generously packed with down making it super lofty. The spaciousness also gives you the option to stuff in an extra quilt if you need to add some warmth. Considering how warm this bag is, it packs down incredibly well. 

If you’re just getting into backpacking the price tag might seem ridiculous but for serious backpackers who value high end gear, it’s a worthy investment. Also, like with all proper winter sleeping bags, the versatility of the Kodiak is limited. It would be way too warm for summer backpacking trips and overkill in mild Spring weather.

The Kodiak MF is also available in a 6 foot and 7 foot version.

The Marmot Trestles 0 sleeping bag is a great option for someone looking for a bag that will keep them warm in frigid temperatures, but doesn’t want to break the bank to invest in an expensive cold weather bag.

This bag is rated to keep you warm in temperatures down to 0°F, so it’s a great bag to take with you to the Cascades in Washington or the Sierra Nevadas in California. The bag itself will keep you toasty and cozy and the hood of the bag will provide extra heat for you.

This bag is made with quality material, including a zipper guard to make sure it won’t snag on your bag when you’re zipping it up. A 3D foodbox at the bottom provides warmth, and will also keep you comfortable by providing enough space at your feet so you won’t feel like you’re sardined into a bag.

This bag is a bit heavy, with the regular size weighing in at about 4 ½ lbs, but it sells at a killer price point. It can be hard to find a reliable backpacking sleeping bag for under $150 and, which is why this is a great option for hikers on a budget.

If you’re on a budget and looking for a highly affordable, cold-bearing sleeping bag, then definitely consider the Kelty Cosmic 0. This bag, although ringing in at a lower cost, will keep you warm down to 2 Degrees Fahrenheit and it comes equipped with all the features you need for a good night’s rest. A draft collar ensures warmth around the neck while the water repellent coating easily wicks away moisture. 

Pack this bag if you’re thinking about a quick, cold weather expedition. You probably won’t want to rely on this bag for long duration expeditions, where you may be spending a lot of time in your tent, but if a quick in-and-out journey is on the docket, then definitely consider saving yourself some money and going with the Kelty Cosmic 0.

If hiking is in your bones, your love of the sport doesn’t magically end in the winter. Well, thankfully sporting goods manufacturers see your obsession and raise you the gear to match it. The Marmot Never Summer, for example, voids the idea of “stepping out of your comfort zone” with your very own comfort zone. 

The sleeping bag makes you feel more like you’re sitting on a rug in front of the fireplace than resting in sub-freezing temperatures. Your entire head will be covered by the hood of this bag and you can even put heating packs in the foot pockets, because it’s impossible to fall asleep with cold feet. Plus, it’s a lot easier to face tomorrow’s summit after getting a good night’s rest tonight.

With zippers galore for a variety of configurations, the Sea to Summit Ascent ACIII is a 0 degree sleeping bag that you can zip together with another bag or unzip completely to lay flat as a warm winter quilt. You can also unzip one side like a standard sleeping bag, half unzip the top layer if you need extra ventilation, or unzip just the foot-box if your feet start to sweat.

The Sea to Summit Ascent ACIII is designed with vertical baffles on the torso, which keep the insulation in place inside the bag and prevents cold spots. The semi-rectangular shape also provides a bit more room than a mummy-style bag, so you can sleep comfortably.
