Survive the summit push.
Meeting the demands of extreme alpine environments, the Big Agnes Croshu UL -20 Degree Sleeping Bag maintains fiery warmth when whipping winds and subzero temperatures threaten to leave you in full-on survival mode. The bag's ultra-light designation makes it an ideal choice for shaving weight, especially when you're hauling up a big wall or trekking across inhospitable terrain.
850-fill DownTek maximizes the bag's lofting power, trapping essential body heat when you're hunkering down on a portaledge for the night, and it uses a hydrophobic treatment that repels outside moisture from compromising its heat-trapping loft. Insotect Flow Construction replaces the traditional baffles employed on many subzero bags. This Flow-Optimized Architecture features Vertical Thermal Channels for rapid and equal distribution of body heat—all without cold spots sapping your warmth inside. It's also contoured to your body's shape for a closer fit that locks in precious heat in extreme conditions, and it reduces the amount of materials needed in materials to result in a lighter bag on arduous adventures.

- Q & A
UL = Unbelievably Light
I have been trying a ton of sleeping bags this past year and the Crosho is a definite standout. 3lbs for a -20 winter bag seems too real to believe. I haven't field tested in the cold and snow yet, but have no reason to think it is not going to keep me warm. Hydrophobic down is a must have, in my book,I'll update this later, once winter camping season gets going. I'm planning some overnight touring trips and stoked to have a warm, light bag to use!
