Extreme cold weather sleeping bags prevent any heat loss, so you can have a successful winter camp-out. They feature zoned insulation, maximizing the thermal efficiency in the most cold prone areas. These sleeping bags are commonly designed with a draft collar, so you can move around at night without worrying about cold air pockets.
