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

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