Understand temperature ratings
Opt for a sleeping bag with a temperature rating below the lowest nighttime temperature you expect when camping.
Choose a sleeping bag shape
There are four main shapes: rectangular, semirectangular, mummy and double. Generally, you want one that gives you room to stretch.
Select synthetic or down insulation
- Synthetic is more affordable, dries faster and provides warmth when damp.
- Down is lightweight, durable and compresses small.
Consider other features
A waterproof shell, snug-fitting hood, extra zippers and even a stash pocket can add durability, warmth and function.

Choose the right fit
