Sea to Summit Reactor Insulated Sleeping Bag Liner

THERMOLITE FABRIC

The Reactor Series Sleeping bag liners and the foot boxes of the Women’s Trek, Talus and Latitude Sleeping Bags use hollow core THERMOLITE fiber to add warmth. Hollow cores fibers trap extra air for insulation (just like the hollow-cores of polar bear or caribou fur). Knitted THERMOLITE fabric is soft and stretchy and comes in three different weights: 80g/m² fabric used in the Reactor and the underside of the Compact Plus liners; a 110g/m² fabric which is used in the Extreme, and the core and foot box of the Compact Plus liner; and the Fleece, the warmest of all the fabrics.
