No longer do you need to be wrapped up like a friggin' gordita when you're camping in frigid alpine environments. While most bags designed for severe cold weather have a restrictive mummy shape, Western Mountaineering's Cypress GWS -30 Degree Down Sleeping Bag is incredibly wide for a roomier, more comfortable fit, yet it's still capable of keeping warm when temps plummet into negative double digits. Of course, when you're well above the tree line, frigid temperatures aren't the only thing you have to worry about--howling winds and relentless snowstorms are also major factors. So Western Mountaineering equipped this bag with windproof and waterproof Gore WindStopper fabric to keep icy gusts, snow, and condensation from robbing all your heat. A stout, insulated draft tube and three-dimensional draft collar keep you warm at the openings, and you can open up the foot box to let your feet breath on warmer nights at base camp.
