Mummy Backpacking Sleeping Bags

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.

How will you be using your liner? 

• For backpackers, a mummy-shaped bag liner helps keep your sleeping bag free of dirt and body oils, helping it last longer. A liner can also be used in place of a sleeping bag in hot climates. 

• For travelers, a rectangular bag liner or travel sheet keeps you separated from bedding of questionable cleanliness or with possible bedbug infestations. 

Which liner material is right for you? 

• Silk: Very lightweight, compact and insulates in cold weather. Absorbent and breathable in warm weather. Price: moderate to expensive. 
• Cotton: Strong, durable and absorbent, but not the lightest or most compact. Price: economical. 
• Fleece and microfleece: Warmer, heavier, soft, moisture-wicking and quick-drying, but the mid- and heavyweight varieties are bulky. Price: moderate. 
• Synthetics (e.g., CoolMax^®): Moisture-wicking, breathable, ideal for humid conditions and stretchy for restless sleepers. Price: moderate. 
• Insulated (e.g., Thermolite^®): Adds enough warmth to greatly extend the range of a lightweight bag. It dries faster than cotton. Price: moderate to expensive.
