But don't just take our word for it, check out some of the pros and cons of some of the main specs.

Our review will pinpoint the major specs to keep in mind when purchasing a rectangular backpacking sleeping bag. Backpacking sleeping bags pack down smaller, so they are ideal when it comes to portability. They are especially designed to be lightweight, making long days out on the trail easier to handle. Designed for warmth, backpacking sleeping bags will keep you cozy on your next outdoor adventure. They are designed to withstand a variety of climates and terrains, so even if you get stuck in a storm or forget to pack some extra layers, you'll have enough protection to sleep through the night.

Rectangular sleeping bags are roomy and spacious, so they are ideal for people who feel too claustrophobic by the tight mummy shape. They accommodate varying sleeping positions, allowing you to sleep in any position you choose. With double zippers, they are perfect for a cozy night of sleeping for two as you can attach two sleeping bags to each other. However, they are not very heat-efficient, creating extra space inside which can weaken the bag's ability to keep you warm. Another downside is that rectangular sleeping bags are quite heavy, so they may weigh you down on long backpacking trips.
