Sea to Summit Silk Blend Sleeping Bag Liner, Mummy, Compact.

The liner is the climatic core of your sleep system - the silk-blend liner adds warmth and luxury to your sleeping bag. Hollow-core Thermolite Pro fibers are reinforced with infrared-absorbing ceramic pigments to create a layer that traps warmth around you. HeiQ's anti-odor technology keeps the liner fresh even after extended use. The drawcord footbox opens and closes for optimal comfort and pairs perfectly with the Sea to Summit sleeping bag's footbox zipper. Sea to Summit's warranty is provided for the life of this product. Designed primarily for comfort, the silk blend liner is made of 72% Thermolite Pro yarn with infrared technology, Thermolite Ecomade fibers, and 28% silk to add warmth to your sleeping bag. This combination creates a soft and luxurious sleeping environment. Comfortable stretch panels along the seams enhance sleep comfort. Shoulder openings and a footbox with drawcord add temperature regulation (matching the Sea to Summit sleeping bag's Free-Flow zipper).
