Top Cold Weather Single Sleeping Bags for 2019


Our review process

We've taken a look at more than 800 sleeping bags, including many different cold weather single sleeping bags. We used our leading artificial intelligence platform to rank each individual sleeping bag based on a number of data parameters. These features range from the temperature rating and the number of seasons to type and weight. The following article will talk about cold weather single sleeping bags in particular, of which we found 180. We hope that this article will help you choose the best one for you.

Wanting to buy a sleeping bag for your next trip but don't know which one? Consider cold weather single sleeping bags. These sleeping bags are designed to be compact, so they'll fit easily in your pack, even if you are short on space. They have enough space for one, fitting more snug and tight for excellent insulation. Single sleeping bags weigh less than double sleeping bags, so if you don't need a lot of sleeping space, they are better for carrying less overall weight.

Preventing any heat loss, these sleeping bags are critical when you're out in the cold for extended periods of time. They are commonly designed with a draft collar, so you can move around at night without worrying about cold air pockets. With insulation running along the length of the zipper, they eliminate weak points along the opening that can allow in cold drafts. Cold weather sleeping bags are more often than not made with feather down, so they provide excellent insulation for winter treks.
