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.

D3O® unique technology is based on the innovation of capturing the benefits of non-Newtonian shear thickening material in polymers that can then be engineered for real world impact
protection solutions. These enhanced properties offer a number of different performance benefits depending on the base polymer used and the intended application. D3O’s global patents
ensure that no other company can offer the same type of protection. D3O® materials are engineered to be fit-for-purpose but as a solutions provider D3O® is also able to customize the
various formulations to a partners specific requirements.
