The Helly Hansen Lifaloft Air Insulator Jacket is a water-resistant jacket for high-output days that require lots of layer changes. Helly Hansen's LifaLoft™ Air insulation delivers breathable lightweight warmth, and its soft exterior helps your body move. When you hit a tough kickturn and flop into the side of the mountain, a PFC-free DWR coating will protect the snow from trickling in. An attached hood even fits under helmets so you can layer some GoreTex over top and reduce wind chill to your neck. Complete the kit with huge pockets to store your skins, and maybe you won't have to lug a big backpack to the top after all!
