With our trusted HELLY TECH® Professional technology, the Alpha is waterproof/breathable and windproof. We used PrimaLoft® Black Eco insulation with clever body-mapping to keep you warm. Our unique H2Flow™ system with strategic mechanical venting enables to you retain or release heat as needed. With a sharpened and articulated fit, the jacket delivers maximum freedom of movement. We added a Life Pocket™ engineered to preserve your phone battery in deep cold, so you can keep up with friends or work while on the slopes. More premium ski features include: an adjustable powderskirt, a detachable and helmet-compatible hood, a neon colored brim, a ski pass pocket, a stretch powder skirt, and wrist gaiters with thumb holes. This is a certified bluesign® product and it contains Ocean Bound recycled materials, which are sourced within 50km of a coastline or main waterway in regions at risk of plastic pollution.
