The Helly Hansen Alpha 4.0 Jacket is a high-tech, pro-level ski jacket that's been designed to meet the needs of even the most seasoned ski fanatic. It's built around a dual-layer shell that offers extreme levels of both wind and water protection, with body mapped PrimaLoft® Black Eco insulation added for all-day warmth. If things get too hot, the H2Flow™ ventilation system allows for easy, fully-adjustable cooling. Pocket space is plentiful on this jacket, the most notable of which is their Life Pocket™+ that ensures your phone stays warm, keeping your battery level high. Care went in to adding a host of ski-minded details throughout the entirety of this jacket, including a helmet-compatible hood, articulated sleeves, a Recco® reflector, wrist gaiters, an adjustable powder skirt, and a handy ski-pass pocket. For those who are serious about their time on the mountain, the Alpha 4.0 Jacket from Helly Hansen is here to help you make the most of it.
