Coleman Adjustable Comfort Sleeping Bag: Need a bag for car camping and don’t want to miss a mortgage payment to cover the cost? Fitting adults up to 5 feet, 11 inches (there’s also a big and tall version), this versatile bag “adjusts” to temperatures ranging from below freezing to 70 degrees. It achieves this versatility with an internal sheet that you can use alone and two separate insulated flaps that cover your upper body and/or legs — kind of like rolling up a burrito. While too heavy and bulky for backpacking, it’s affordable and warm enough for typical three-season camping. 5 lbs., 9 oz. $60

Nemo Kyan 35: When it hits stores in the spring, this bag will be tough to beat in terms of performance for the dollar. Packed with water-resistant, lightweight and highly compressible PrimaLoft Silver synthetic insulation, this summer-weight bag promises packability that competes with down. A thermally efficient mummy shape and close-fitting hood help trap heat, while Nemo’s Thermo Gills — two zippered torso vents that open up to just an uninsulated nylon panel — help release heat in mild temps. Bonus: It comes with a compression stuff sack. 1 lb., 12 oz. $200

Therm-a-Rest HyperionFor adventures that demand a light pack without compromising nighttime comfort, high-quality down is the way to go, and this packable, ultralight mummy ranks among the lightest 32-degree bags. Stuffed with 900-fill Nikwax Hydrophobic Down, it will retain loft when wet up to 60 times longer than untreated down. Lightweight but thermally efficient construction technologies include box baffles with mesh walls that maximize loft and eliminate cold spots, a ThermaCapture lining that reflects body heat, zoned insulation and a draft collar. 1 lb. $370

Big Agnes Picket SL 30Want a synthetic bag that stands out for its roominess and comfort? The Picket features unique stretch side panels that allow much more mobility than a traditional mummy bag. The stretchy PrimaLoft Gold Active insulation in those panels moves with the fabric, preventing cold gaps. PrimaLoft Silver insulation throughout the bag’s body retains its ability to trap heat even when wet, and the offset quilted construction and vaulted foot box all make the bag highly thermally efficient. 2 lbs., 4 oz. $260

Sierra Designs Nitro 800 20-DegreeSometimes comparing critical specs like temperature rating, insulation, weight and price speaks volumes about a bag’s value — and the Nitro scores high in that contest. Stuffed with PFC-free, water-resistant, highly compressible and warm-for-its-weight 800-fill-power DriDown, this bag can push the outer edges of three seasons. Although it weighs fewer than 2 pounds, it has generous space with a 62-inch girth at the shoulders, 56 inches at the hips and 40 at the feet. The roomy hood closes up snugly, and a half-length, 40-inch zipper and the zipperless foot vent let you cool off at both ends. 1 lb., 13 oz. $330

Feathered Friends Snowbunting EX 0: Heading into the winter backcountry? More than comfort is at stake, so don’t mess with inferior bags. A leading winter sack, the EX 0 is stuffed fat with 900-plus-fill goose down feathers, yet it weighs in at fewer than 3 pounds — rare for a zero-degree bag. The waterproof-breathable Pertex Shield EX laminate shell fabric with a DWR (durable water-repellent treatment) sheds dripping condensation inside a tent or falling snow if you bed down outside and get surprised by weather. It also breathes well enough to keep from getting clammy on milder nights. 2 lbs., 13 oz. $599

Klymit KSB 20If you’re getting serious about your backcountry adventures, try Klymit’s KSB bag. The 650-fill down won’t absorb much moisture and dries quickly. Its flexible baffles keep the bag close to your body, ensuring you won’t lose any heat as you toss and turn. With a 20-degree rating and especially warm toe box, this bag is built for any three-season conditions. Cool feature: The KSB features stash pockets in which you can store small items nearby. 2 lbs., 8 oz. $250
