About this product
The Coleman PEAK1 0 Mummy Down Sleeping Bag is built for backpacking, offering a 0 degrees Fahrenheit (negative 17.7 degrees Celsius) temperature rating with an ISO-tested lower limit of 8 degrees Fahrenheit and a comfort rating of 21 degrees Fahrenheit. It is filled with 650-fill-power duck down that carries a durable water repellent treatment to maintain loft in damp conditions. The shell is a recycled 20-denier ripstop nylon and the liner is 40-denier nylon, keeping packed weight to approximately 1,361 grams (3 lbs. 11.97 oz.) in regular size. A built-in sleeve accommodates a sleeping pad to create an integrated sleep system, preventing you from rolling off during the night (pad sold separately). The form-fitting mummy hood, neck baffle, and Thermolock draft tube work together to seal in warmth, while the ZipPlow zipper design and internal webbing guard against snagging. Hip girth measures 46 inches in the regular size, which packs down to 15.2 liters in the included compression sack. A mesh storage bag and a 5-year limited warranty are also included.

What people are saying
Reviewers consistently praise the Coleman PEAK1 0°F Mummy Down Sleeping Bag for its impressive warmth, lightweight feel, and compact packability, with many noting it punches above its price point compared to premium outdoor brands. The 650-fill duck down, DWR shell, and integrated sleeping pad sleeve are frequently highlighted as standout features. Build quality, including stitching and zipper durability, earns repeated compliments. The most common criticism is that the temperature rating feels optimistic, with some users finding the bag more comfortable in the upper 20s to 30°F range than at a true 0°F. A secondary complaint is the snug fit, which can feel restrictive for broader or heavier-set sleepers.
