Top Lightweight Rectangular Sleeping Bags


Our review process

We've taken a look at hundreds of sleeping bags, including plenty of different lightweight rectangular sleeping bags. We used our machine learning technology to score each individual sleeping bag based on several data points. These features range from liner material and number of seasons to type and weight. The following guide will talk about lightweight rectangular sleeping bags in particular, of which we found 69. We hope that this article will help you pick the best one for you.

When trying to choose your next lightweight rectangular sleeping bag, there are important things you'll want to know. These sleeping bags pack down to 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 great 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, weighing only a few pounds. However, they are typically not as warm, so they aren't designed for sleeping out in very low temperatures. Rectangular sleeping bags have a super roomy design, which makes it easy to get comfortable night, giving you enough tons of space stretch out. They accommodate varying sleeping positions, giving you plenty of room to get comfortable, regardless of your sleeping position. They feature double zippers, so they can double as an over blanket.
