Western Mountaineering Flylite 36°F

Introducing the Flylite down sleeping bag.  It was designed as a product to celebrate Western Mountaineering's 50 year commitment to manufacture the lightest, most compressible sleeping bags in the world.   This sleeping bag was designed specifically for the global lightweight gear community (triple crown thru hikers,  trail runners, bike packers, and friends with cool names like “Psycho Haiko”).   The effort has resulted in the world's lightest weight down sleeping bag that is fully baffled (i.e. no quilted/sewn through construction).  The tiny micro baffles create just enough separation between the lining material and the outer shell fabric to eliminate cold spots. 10 denier fabric lining and 10 denier nylon taffeta shell fabric with C-zero DWR with the finest polish 850+ goose down and a super light #3 ykk half zipper all contribute to the impressive specifications and performance.  This bag weighs just under 14 ounces ounces/395 grams in the regular length and packs down to the size of a Nalgene bottle.   Lower limit rating of 36 F/ 2C.
