About Extreme Clod Weather Sleeping Bags Rated From 0 Degrees and Colder:
For Winter and icy mountain expeditions you need a sleeping bag that can withstand sub-zero temperatures. -40 to 0 degree sleeping bags transcend the realm of comfort and enter into the necessary-for-survival zone.
Hod, the Norse god of all things dark and cold, could find himself snug and toasty even in the extreme cold of an Everest expedition, provided that he had the right sleeping bag. Even if you aren’t a deity you can benefit from insulation that keeps the biting cold at bay.
On an extreme adventure staying alive is serious business, a good sleeping bag not only protects you from the cold, it lets you sleep comfortably through the night so you can be ready for any challenges that the next day might bring.
