The waterproof, windproof Storm Shift Pants are made of fully PFC-free GORE-TEX material-that means the fabric, membrane and DWR finish do not contain perfluorinated chemicals. A unique liner is warm and wicks moisture to provide lasting storm protection and comfort for skiers and boarders getting out in all types of conditions. With a refined fit, clean styling and technical features, Storm Shift Pants are built to complement a rider's natural movement. Fair Trade Certified sewn.
