  • Our take on the Kelty Cosmic 20

    The Kelty Cosmic 20 is a down-filled mummy bag rated to 20°F and weighing about 2 lb 7 oz in Regular. It uses 550-fill down in horizontal baffles, a recycled shell and liner, and a PFAS-free DWR finish. It suits backpackers and campers who want a light, packable down bag without paying premium prices. Against pricier 800-fill bags it is heavier and bulkier, and owners report the 20°F rating is optimistic for cold sleepers.

    Questions and answers

    Is the Kelty Cosmic 20 warm enough for freezing nights?
    Many owners say it is comfortable in mild three-season weather but runs cold at or below freezing. Cold sleepers should treat it as a 30°F bag or add a liner.
    How does it compare with the Kelty Cosmic Down 20?
    It is the current version of that bag, with recycled shell and liner fabrics and a PFAS-free DWR. The fill and general shape carry over.
    What sizes does it come in?
    Regular, Long and Short, in men's and women's versions. The Long measures 84 in long with a 64 in shoulder circumference.
    Is it good for side sleepers?
    The mummy cut is narrow at the knees and the footbox is natural-fit, so side sleepers often find it restrictive. Stomach and back sleepers tend to be happier.
    What is included with the bag?
    The bag comes with a stuff sack. A zippered internal stash pocket and draft tube are built in.
    Can it be used for winter camping?
    No. It is a three-season bag. For below-freezing trips, pair it with a warmer bag or a liner.
    Where is the Kelty Cosmic 20 cheapest?
    At Amazon, for $179.95, as of our latest check.
    Where can I buy the Kelty Cosmic 20?
