Western Mountaineering
Bristlecone MF, 6'0"
-10oF, 850+ down filled winter sleeping bag
This bag is built big and warm and big! 69" of girth at the shoulder and 48" of girth at the foot. Crammed with 42 oz. of 850+ down yields an unrelenting 8" of simmering loft that keeps you heated to -10o. A large draft tube and the down filled collar make certain that winter remains outside. With 2 zippers it can be zipped to another Western Mountaineering mummy bag or unzipped to lie flat. In spite of its roomy proportions the Bristlecone weighs only 4 lbs. 2 oz.
