Sierra Designs Backcountry Bed 600 Sleeping Bag 37 Degree Down

Sierra Designs took a drastically different approach to designing the Backcountry Bed 600 Sleeping Bag so you can sleep in the wilderness and feel more like you're in your own bed at home. Free from extraneous hardware like bulky zippers and drawcords, this intuitive bag features an oval shaped opening with an integrated comforter that helps it adapt to variable temperatures. You can tuck the comforter's sides snugly beneath you and stay warm in temps as low as 30 F, or you can pull the comforter out for the warmer nights. Its unique mummy design allows you to sleep on your stomach or side as well as your back, which is excellent because most mummy bags only let you sleep comfortably on your back. Sierra Designs stuffed this bag with 600 fill duck down insulation that was treated with DriDown to give it water resistant qualities so you can stay warm even if moisture seeps through your tent. Sierra Designs built the Backcountry Bed's shell out of ripstop for durability and the liner out of taffeta for your comfort. This bag also features insulated pockets for your arms so you never wake up in the middle of the night because your hand slipped out of the bag and is slowly chilling. There's also an integrated sleeve for your sleeping pad so you never roll off of it during the night and wake up on the rocky ground. This sleeping bag is light enough for backpacking and warm enough for chilly nights.
