Liner uses
- Backpacking: A mummy-shaped liner can add 5° to 15°F of warmth to your bag. It also helps your bag last longer by protecting it from dirt and body oils.
Traveling: A rectangular liner separates you from unclean bedding.
Liner materials
- Silk: Very light, compact and insulates in cold weather. Absorbent and breathable in warm weather. Price: moderate to expensive.
- Cotton: Strong, durable, absorbent. Not the lightest or most compact. Price: economical.
- Fleece and microfleece: Warmer, heavier, soft, moisture-wicking, quick-drying. Mid- and heavyweight varieties are bulky. Price: moderate.
- Synthetics: Moisture-wicking, breathable, stretchy. Price: moderate.
- Insulated: Adds enough warmth to greatly extend the temp range of a lightweight bag. Price: moderate to expensive.
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. For camping, you want one that gives you room to stretch.
Decide between synthetic or down insulation
- Synthetic is more affordable, dries faster and provides warmth when damp.
- Down is lightweight, durable and compresses small.
Other features to consider
A waterproof shell, snug-fitting hood, extra zippers and even a stash pocket can add durability, warmth and function.
