Thermolite

THERMOLITE® insulation, designed for ultimate performance, is made from specially engineered fibers to achieve a high CLO value with low weight. THERMOLITE® HL-1 high loft insulation is a fiberfill constructed with a unique 3D crimp of hollow-core and solid fibers, which provide excellent lightweight warmth with superior durability.

The THERMOLITE® insulation lofts up inside the Air Sprung Cells™ to prevent convective heat loss from your warm body to the cold ground. Exkin Platinum® and THERMOLITE® are combined to great effect in each of the Insulated versions of our mats.
