Our review process

We've taken a look at hundreds of sleeping bags, including plenty of different large cold weather sleeping bags. We used our advanced machine learning engine to rank each individual sleeping bag based on several data entries. These features range from the temperature rating and the number of seasons to cleaning options and designs. The following article will talk about large cold weather sleeping bags in particular, of which we found 46. We hope that this article will help you choose the best one for you.

We've reviewed large cold weather sleeping bags and want to let you know about both the pros and cons. Preventing any heat loss, these sleeping bags are critical when you're out in the cold for extended periods of time. They feature draft tubes, which run the length of the bag behind the zipper to help prevent warm air from escaping. Cold weather sleeping bags are usually designed with a draft collar, keeping the warm air around your torso in and cold air out. They are more often than not designed with feather down, so they provide excellent insulation for winter treks. These sleeping bags are made from thicker materials than smaller and shorter sleeping bags, so they are super soft and cushioning. They are very spacious, so you'll have plenty of room to stretch out comfortably.
