Western Mountaineering Caribou MF Sleeping Bag: 35F Down Navy Blue, 6ft/Left Zip

The people at Western Mountaineering are pretty proud of their Caribou MF 35 Degree Down Sleeping Bag, with its MicroLite XP breathable microfiber yarn that's densely woven to create a high thread-count material that naturally fends off moisture. Weighing in at a mere pound and a quarter, this is Western Mountaineering's lightest-weight Microfiber Series bag, ideal for summers spent hiking in the mountains or touring the country on two wheels.
