Western Mountaineering Tioga Silk Sleeping Bag Liner – Mummy Long

Lightweight warmth and bag protection for adventurous nights

The Western Mountaineering Tioga Silk Sleeping Bag Liner in Mummy Long is designed to travel with you, offering a featherweight layer that adds warmth without adding bulk. Silk fabric is exceptionally soft, breathable, and incredibly compact, making it an ideal companion for backpacking trips where every ounce and every inch of pack space matters.

Why silk? Silk delivers a balance of insulation, moisture management, and packability. In cooler camps, the liner can contribute an extra insulating layer to your setup without translating to a heavy add-on. In warmer conditions, it acts as a breathable shield against dirt and grime, helping to keep your sleeping bag cleaner on dusty trails or in humid environments. The result is a more comfortable night’s rest with less fuss while you’re on the move.
