Warm up without feeling weighed down, our proprietary LifaLoft™ insulation is lighter and warmer than standard insulation. The Kensington Winter Jacket features both the LifaLoft™ technology and Black Eco Insulation from Primaloft® for when you need to stay warm for long hours in cold conditions. The Helly Tech® Professional membrane allows the jacket to stay waterproof & breathable, with articulated sleeves, detachable hood and adjustments on the cuffs to create the perfect fit.
