Helly Hansen Alpha 4.0 Jacket

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.
