Full length zip baffles and around the shoulders prevent cold spots and heat loss and the Shark Toe footbox design allows the foot to rest in its natural position. The hood wraps close to the face with the aid of a drawcord and the included compression stuff sack ensures optimum packability. The regular length is suitable for women up to 170cm tall.
