Our review process

Our team has collected, researched, and analyzed information on hundreds of different kinds of sleeping bags in order to show you our top rated sleeping bags today. We then further sub-categorized them and looked more specifically at 12 different lightweight winter sleeping bags. In our research, we took into consideration a variety of different main features among the 28,000 different data points and combined it with customer reviews to inform you of the top lightweight winter sleeping bags available. But don't just take our word for it, check out the benefits and disadvantages of some of the main specs.

We've reviewed lightweight winter sleeping bags and want to let you in on a few things. Lightweight sleeping bags pack down into a small size, so if you're planning on bringing along a lot of other gear, they are great for getting rid of some extra bulk. Since extra weight can make a hike or trek more physically demanding, they are good for beginners. They are easy to carry, so they won't hurt your shoulders. However, they are typically not as well-insulated, so they aren't designed for sleeping out in very low temperatures. These sleeping bags feature tough insulation, providing enough warmth to keep you comfortable on chilly summer nights, cold spring and fall conditions, and freezing winter temperatures. They are for serious cold and snow conditions, so they are not suitable for use outside of the winter seasons, since you will feel overheated in temperatures above freezing. They have a waterproof coating, so if you plan on sleeping out in snow, they will keep you warm and dry throughout the night.
