It’s extremely important, when you find yourself in extreme cold weather, to be able to get warm. If you have no way to get warm and stay warm you’re in serious trouble. So it’s very important to have a good extreme cold weather sleeping bag in such a situation, since that will likely be your main way, if not your only way, to get warm. And even more, you need a sleeping bag that you can depend on, that wont fail you when you end up needing it most.
Extreme Cold Weather Sleeping BagWhat to look for when looking for an extreme cold weather sleeping bag.
- Water Resistant – For extreme cold weather it’s a very good idea to have a water resistant or even waterproof sleeping bag. A wet sleeping bag is not a warm sleeping bag, and a failing sleeping bag can make for a dangerous situation when you find yourself in extreme cold weather.
- Temperature Rating – It’s important to plan ahead for extreme cold weather, and get a sleeping bag with a temperature rating that can handle it, and keep you warm. You can always throw on a few layers to wear inside your sleeping bag, but it’s more comfortable, and safer, to get a sleeping bag with an appropriate temperature rating.
