Big Agnes Backpacking Sleeping Bags

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.
