The Eira Women's Northern System 3 in 1 Jacket incorporates a weather stopping shell with a removable insulating layer that is stylish enough to wear on its own when you head out for drinks after a day on the slopes. The shell jacket features a microporous membrane, fully taped seams, and a DWR finish to stop wet winter weather dead in its tracks. The liner jacket brings the warmth to the party with 100g Primaloft Silver insulation and a soft satin lining. All the features are right where they need to be to have a comfortable day on the slopes on this technical and versatile jacket. A removable powder skirt locks out snow when you're getting first tracks on a powder day, and the adjustable cuffs and hem let you seal in heat when things start to get really cold. Two internal pockets keep your phone and mp3 player secure, while four zippered external pockets keep you snacks, and season pass secure. Two underarm vents let you lose excess heat for a quick cool down, and YKK Aquaguard zippers prevent moisture from seeping in through any of the zips.
