10 Best Klymit Sleeping Bags
for February 2024

MOOZ Themes editors select recommendations independently, so your purchase through our link may earn us a commission.

Sleeping bags, by their very nature, are thick, bulky blankets designed to be worn at night. These blankets come in a variety of styles and materials, including down, synthetic, and fleece, with prices ranging from under $50 to over $300.

Sleeping bags come in a variety of shapes, sizes, and weights, and each one is designed to keep you cozy and warm in the backcountry, on a camping trip, or in an RV. Sleeping bags come in traditional mummy bags, which hug your body closely, and rectangular bags, which spread your body out more. Sleeping bags also come in a range of temperatures, from below freezing to 80 degrees, and range from 0.5 to 30 pounds, so it's important to choose the right bag for the weather.

Our sleeping bags are put through extensive testing in the MOOZ Themes Reviews Lab, where we evaluate performance, such as warmth, weight, and durability, as well as ease of use, such as set up, packability, and storage. Our testers also evaluate how warm the sleeping bag is, how quickly it warms up, and how warm it stays throughout the night. Here are the best sleeping bags of 2022, according to testing and consumer reviews:

by Klymit

Extra warm: innovative dual fill system is rated for 20f temperatures, 650 power fill down on top side of bag, and double layer synthetic batting beneath ensures the best of warmth and comfort.

KLYMIT Wild Aspen Lightweight 20 Rectangle Degree Sleeping Bag

by Klymit

Rectangular design allows plenty of room to stretch out

The wild Aspen 20 is our pick for the best lightweight sleeping bag for camping because it's warm, compressible, and - thanks to its synthetic fill insulation - packs down easily into a sac. The wild Aspen 20 is also reasonably priced, making it one of the best values on our list. Our testers liked that the bag has a drawcord closure, which helps to keep the cold out. The bag is also relatively light, at 5.1 pounds, which makes it easy to pack up and haul around. What's particularly nice is that the wild Aspen 20's insulation is breathable, so it doesn't trap in heat or make you sweat. The bag has a 20-degree temperature range, which is a good temperature for sleeping outdoors on cold nights. The wild Aspen 20 is also waterproof, so it's a good choice if you plan to camp in rainy conditions. The bag's fabric is water repellent, so you won't have to worry about getting soaked while sleeping. The bag comes with a drawcord bag closure system, which makes it easy to open and close. The bag also comes with a stuff sack, so you can store it neatly. The wild Aspen 20 is lightweight, so it's easy to carry, and the insulation is breathable, so you won't feel hot while sleeping.

Klymit KSB 0°F Large Dual Fill Sleeping Bag, Great for Cold Weather Camping, KSB 0 Large (Hybrid), Gray

Klymit KSB 0°F Large Fill Dual Sleeping Bag

by Klymit

Winter weather capable: innovative dual fill system is rated for 0F temperatures, 650 power fill down on top side of bag, and double layer synthetic batting beneath ensures the best of warmth and comfort.

The KSB 0°F is a large sleeping bag, and it's well-suited for campers who like plenty of insulation. The KSB 0 is a roomy hybrid sleeping bag, with a compression sack that compresses the bag down to the size of a football, but the bag still has plenty of padding. The cut is slim, so it's best for campers who aren't overly tall or heavy. The bag is warm, reliable, easy to use, and easy to clean. The two-way zipper and draft collar are great features, and the soft drawcord at the hood makes it easy to adjust. The bottom of the bag also has stretch baffles, which help the sleeping bag maintain its structure while staying comfortable. The bag has a medium fill, but it's close to the top of our recommendations. The KSB 0°F sleeps well, but it's a bit on the heavy side, and it's pricier than the competition.

Klymit KSB 0°F X-Large, Oversized Sleeping Bag, Great for Cold Weather Camping

Klymit KSB 0°F X-Large

by Klymit

Winter weather ready: innovative dual fill system is rated for 0F temperatures, 650 power fill down on top side of bag, and double layer synthetic batting beneath ensures the best of warmth and comfort.

The Klymit KSB 0°F X-Large, Oversized Sleeping Bag is roomy enough for two, and warm enough for three-season camping in cold weather. The bag's temperature rating is 0°F, but the temperature range is 35°F to 60°F. We tested it at a temperature rating of 0°F in January, and it was comfortable down to about 40°F. The KSB 0 is much lighter than the 5. 5-pound bag we tested in the previous top pick. It's packed with features, including a dual-layer construction, a full-length zipper, and a stretch baffle system that locks the bag in place. The stretch baffle system also ensures a good fit, and the head-to-toe coverage that mummy hood with draft collar and draw cord provides. Like the 5. 5-pound bag, the KSB 0°F is a thermoregulating bag, so you don't have to worry about the bag getting too hot. The bag's draft collar and drawstring help reduce heat loss, and the oversized foot box was comfortable enough for two of us to sleep comfortably. The bag is also inflated with high-performance, lightweight Klymit Performance 2. 0 Pro insulation, so you'll stay warmer and more comfortable. The KSB 0°F is big enough for two, but it's a little too roomy for three, so three campers should pair up and share the bag.

Klymit KSB 35°F Large Sleeping Bag, Great for Camping and Backpacking

Klymit KSB 35°F Large Sleeping Bag

by Klymit

For cooler nights: innovative dual fill system is rated for 35F temperatures, 650 power fill down on top side of bag, and double layer synthetic batting beneath ensures the best of warmth and comfort.

The KSB 35°F Large Sleeping Bag is a comfortable, spacious sleeping bag for camping and backpacking. Weighing in at 2. 1 pounds, it's light enough for backpacking, but roomy enough to accommodate most campers. The KSB 35°F is a large bag, so (like most sleeping bags) it's best for campers who weigh 130 pounds or less. The bag is roomy enough to accommodate most people, but taller campers may find that the sleeping bag is too short. The bag is also fairly pricey, but it's comfortable, and it's an excellent option for campers who want a versatile sleeping bag that they can use on multiple trips.

Klymit KSB 30°F Double Two Person Sleeping Bag, Great for Car Camping, Backpacking, and Couples Camping, 2-PERSON

Klymit KSB 30°F Double Person Two Sleeping Bag

by Klymit

Room for two: thoughtfully designed for 3-season comfort. The Klymit ksb double features enough room and individual draft covers to allow for each Sleeper to control their sleeping experience.

The KSB 30°F Double is just what its name promises: a water-resistant double sleeping bag designed for two campers. It's warm enough for two adults to sleep comfortably at temperatures down to 30°F, and it's filled almost entirely with down, which means it's lightweight, comfortable, and compressible. Its 650 power fill down on top side makes it feel just as warm as our previous top-scoring double bag, the REI Co-op Down Sweater 30°F Double, but it's rated for 30°F, so it packs much smaller. However, it's not quite as warm as our current top pick, the Therm-a-Rest NeoAir XLite 30°F Double, which packs smaller, sleeps warmer, and is lighter. The KSB 30°F double also packs less compactly than the NeoAir XLite 30°F Double. It's a little bulkier, too, at 7 pounds, 5 ounces, versus 4 pounds, 8 ounces. The bag's 3-1/2-inch thick quilting provides plenty of insulation, and the bag's chest, foot, and hood adjustments let you customize the fit.

Klymit KSB 0 Degree Luxury Sub Freezing Sleeping Bag with Stretch Baffles, Black, Regular

Klymit KSB 0 Degree Luxury Sub Sleeping Freezing Bag with Stretch Baffles

by Klymit

SLEEP COMFORTABLY EVEN DURING BITTER COLD NIGHTS: Large draft tubes and over stuffed with the best synthetic insulation provides a warm night at sub freezing temperatures

The KSB 0 Degree Sleeping Bag from Klymit is one of our favorite sleeping bags, and the best rated model in our roundup. It's packed with features, including a stretch baffle construction that makes it super comfortable, a mummy hood with adjustable neck collar, and 2-way zippers that allow ventilation. Plus, it's incredibly warm. The bag's 20D nylon fabric feels soft and quiet, and it's insulated with Klymalite synthetic insulation. The bag's temperature rating is 0 degrees, and it's filled with 0.6 ounces of Klymalite, which we found to provide plenty of warmth. The bag's fit is snug, so it doesn't add extra room, but its stretch baffle construction ensures that the bag doesn't shift during the night. The bag's design also makes it ideal for temperatures as cold as -10 degrees. The bag's 2-way zippers are solid, and each zipper is insulated with Klymalite so it provides warmth even when the weather gets cold. The bag's mummy shape is warm and snug, and it features an adjustable neck collar that can be tightened to help reduce heat loss in cold sleepers. It also packs easily, and it's light enough to carry over long distances. The only drawback is that it's not suitable for warm weather. This bag is warm enough for temperatures as cold as -10 degrees, but it's not warm enough for temperatures as warm as 20 degrees.

Wild Aspen 0 Regular Sleeping Bag - Green

Klymit Wild Aspen Regular 0 Sleeping Bag

by Klymit

Lightweight and durable micro polyester shell resists water and abrasion

The Wild Aspen 0 sleeping bag is an entry-level bag, but it's well priced at about $40, which is at the lower end of our price range. The bag has a mummy-style hood that adjusts up or down, and is snug enough to keep your head and neck warm, but not so tight that it's uncomfortable. The bag has a draft tube that keeps cold air out, and comes with a compression sack, making it easy to stuff into a pack. The bag has a generous amount of insulation, so it's warm enough for temps down to 30 degrees Fahrenheit, and keeps you toasty in temperatures as low as 20. However, the bag is best suited for camping in mild weather, because in cold weather, the draft tube can cause the bag to leak.
