Heading to the Arctic? or the top of a Himalayan mountain? If so you've found the right bag, with a comfort rating of -30 and a limit rating of -40 you shouldn't be getting cold anywhere other than Antarctica in the winter.

These bags are designed with climbing expeditions in mind and extra room compared to a standard mummy sleeping bag to accommodate clothing inside as required. Th Hydronaute Xt laminated face fabric on the bag keeps moisture from coming through the exterior of the bag but allows adequate breathability for temperature and moisture regulation. It is designed to improve functionality with a Cordless Collar System and to improve performance using vertical baffles for insulation efficiency.

Comfort Rating (Cold Sleepers/Women): -30°C
Limit Rating (Warm Sleepers/Men): -40°C
