The Women's Arc'teryx Sentinel Shell Jacket is a waterproof shell for big mountain freeriders. Built with 3L ePE GORE-TEX for waterproof, windproof, breathable performance, the elements stay out so you stay dry, comfortable, and can keep on riding (or skiing). Pit zips offer easy heat dumping, pockets inside and out offer space for stashing hat, gloves, phone, and RFID pass, and the powder skirt keeps snow from getting in on deep powder days. Throw the StormHood over your helmet, and whether you're taking the next lift or beginning the journey on foot, you're ready for the snow.
