Top Lightweight Backpacking Sleeping Bags


Our review process

We've taken a look at more than 800 sleeping bags, including many different lightweight backpacking sleeping bags. We used our advanced AI platform to rank each individual sleeping bag based on several data points. These features range from the temperature rating and the number of seasons to cleaning options and designs. The following guide will talk about lightweight backpacking sleeping bags in particular, of which we found 107. We hope that this guide will help you in your pick.

Before deciding on your next lightweight backpacking sleeping bag, we think there are some things you'll want to know. Lightweight sleeping bags pack down into a small size, so they are less bulky when rolled up. Since extra weight can make a hike or trek more physically demanding, they are designed for people who haven't gone backpacking or camping before and want to start with a lightweight bag before advancing. They are easy to carry, helping you move on the trail faster, farther and more comfortably. However, they are typically not as warm, so they aren't designed for sleeping out in very low temperatures.

Backpacking sleeping bags pack down smaller, making them suitable for alpine climbing where weight and volume are critical. They have a lightweight design, which makes them ideal for carrying around on your back during long hikes. They have superior warmth, so they are better insulated and lock in the heat. Backpacking sleeping bags are designed to withstand a variety of climates and terrains, standing up to wear and tear for those extreme outdoor trips.
