Related Expert Advice articles

Do I really need a backpacking-specific bag?

Yes. These sleeping bags are lighter, pack down smaller and are more efficient at keeping you warm compared to ones for camping.

Understand sleeping-bag weight

Insulation type and bag shape affect weight the most. Always consider bags of a similar temperature rating when comparing loads.

Choose the right fit
Many sleeping bags come in regular, long and short sizes. Review the bag's size specs for the best fit.

Consider other features
Draft-blocking details, a snug-fitting hood, extra zippers and even a stash pocket can add more durability, warmth and function.
