We've taken a look at extreme cold weather single sleeping bags and wanted to let you know about both the pros and cons. Single sleeping bags provide a compact packing solution, so they'll fit easily in your pack, even if you are short on space. They come with enough space for one, providing excellent heat efficiency to the sleeper inside. These sleeping bags are lighter than double sleeping bags, so if you don't need a lot of sleeping space, they are better for carrying less overall weight.

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. They are usually designed with a draft collar, so you can move around at night without worrying about cold air pockets. Extreme cold weather sleeping bags feature draft tubes, which run behind the zipper to help keep warm air from escaping. They are more often than not made with feather down, so they have an excellent warmth-to-weight ratio.
