XR-Performance weatherproofing technology employs microporous laminations and coatings to produce
durable, breathable and waterproof products for use in the most extreme climates in the world. These
coatings and laminates are combined with a variety of durable shell fabrics and insulation systems to create
weatherproof barriers against severe conditions and temperatures in HMK products.

All levels of XR-Performance Weatherproofing laminate an advanced
microporous membrane to the shell fabric, creating a durable, highly
breathable and extremely waterproof shield against extreme conditions
and varying temperatures.
