We upgraded our iconic resort ski jacket Lifaloft™ insulation, so it's even lighter and warmer than before.  The Alpha jacket is perfect for passionate skiers who don't want to pack a lot for adventures. Like always, it has the thoughtful technical details that keep you comfortable all day on the mountainside. Underarm vents enable you to regulate your body temperature during high output skiing. A water-resistant exterior protects you from light precipitation. Both the hood and powderskirt are detachable; the hood is helmet compatible, too. Additional ski features include a Recco® Advanced Rescue system for findability, a Life Pocket+™ to keep your phone battery alive in cold, a ski pass pocket and a goggle shammy.
