The Marker Celsius GTX women's insulated ski jacket is constructed from Gore-Tex® waterproof, breathable shell fabric. You know you'll stay cozy and dry no matter what the mountain throws at you. This all-mountain piece is one of Marker's warmest jackets. Waterproof zippers, pit zips, a storm hood, and a powder skirt all play their roles to help you enjoy your day-whether its bluebird or blizzard conditions.
