Marmot 3-season Sleeping Bags

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.
