The Browning Camping Denali Wide Sleeping Bag - 30 Degrees, Clay is a wide mummy sleeping bag featuring the Techloft insulation: multi-hole staple-length micro-denier fibers with a siliconized finish. Together with its 2-layer construction designed to avoid cold spots this should keep you cosy and warm. The insulated chest and zipper baffles keep the heat in and cold drafts out. It comes in a handy compression bag so it's ideal to take camping, backpacking, hiking and on any freezing outdoor adventure. This version keeps you comfortable down to -30 C so it is suited to places that are regularly below freezing at night.
