PrimaLoft®

This ultralight synthetic insulation stays warm in cold and wet conditions, and is just as compressible as down.

Why PrimaLoft?

Treks in subfreezing climates threaten to push the average body temperature to dangerous levels. Combat the cold with PrimaLoft fabrics which form tiny air pockets that trap body heat and keep the elements out—even in rain and snow.

How Does It Work?

Water resistance, engineered. Ultrafine fibers create surface tension that prevents moisture from penetrating the garment, while also allowing vapor to escape for breathability.
