Western Mountaineering Flylite 34 Sleeping Bag Left Zip Orange/Grey 6ft 0in. It was designed as a product to celebrate our 50 year commitment to manufacture the lightest most compressible sleeping bags in the world. We feel that this sleeping bag is a product to show the global lightweight gear community (triple crown thru hikers trail runners bike packers and friends with cool names like Psycho Haiko) that we have been listening and taking your feedback into consideration. Our effort has resulted in the worlds 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.
