Kelty Light Year Down 0 Degree (2010) Sleeping Bag

Product Highlights

Updated for 2010! The lightweight, compressible Kelty Light Year Down 0 Degree sleeping bag offers 4-season performance at an affordable price. Warm and packable, the mummy-shaped Light Year Down 0 Degree is ideal for cold weather backpacking.

In an effort to standardize temperature ratings and properly inform consumers, European Norm (EN) testing uses a thermal mannequin to determine the performance of a sleeping bag in a range of temperatures. The Comfort rating is meant to reflect the temperature at which an average adult woman (132 lbs) can enjoy a comfortable night of sleep and a Lower Limit rating is meant to show the temperature at which an average adult male (176 lbs) can enjoy a comfortable night’s sleep. A third rating, Extreme, is meant only to show the survival rating for a “standard” woman and is not advisable for use in making buying decisions for general use. NOTE: The testing assumes that the user of the sleeping bag will be using a sleeping pad of 1” thickness and wearing long underwear, a hat and socks. Kelty bases its assigned temperature ratings based on the EN Lower Limit and the assumption that you will be utilizing both a sleeping pad and a tent.

The Light Year Down 0 Degree sleeping bag is insulated with 650-fill goose down. Down has a soft, comfortable feel and continues to be the insulation with the best warmth-to-weight ratio. The feathers and fibers hold body heat and are very easily compressed, so the bag takes up less space in your pack. NOTE: The one downfall to this insulation is that it loses much of its ability to maintain warmth when it gets wet.

Slant-baffle construction with chevron stitching eliminates cold spots, keeping outside air from reaching the inside of the Light Year Down 0 Degree. A contoured hood with an insulated baffle, an insulated full baffle collar and a draft tube behind the hip-length zipper combine to further insulate against the cold. In balmier weather, an integrated, zippered foot vent allows for added ventilation. A polyester microfiber liner provides internal comfort.

Other features found on the Light Year Down 0 Degree bag include internal liner loops, external snap loops that allow the bag itself to be used as a liner, sleeping pad security loops and hanging loops for convenient storage.

The Kelty Light Year Down 0 Degree sleeping bag is available in Reg (fits up to 6'0") and Long (up to 6'6") lengths. An ultra-light compression stuff sack and storage sack are included.
