Bluebird or blower, in-bounds or out, the Black Diamond Factor Shell is our go-to, do-it-all ski jacket for hundred-day seasons and bell-to-bell days. Featuring our BD.dry(TM) waterproof/breathable/ windproof solution for uncompromising protection, the Factor has a soft interior lining for added comfort and extensive pocket storage for small essentials. Extended, two-way zippered armpit vents let you dump excess heat quickly on the skin track. An integrated powder skirt is a second line of defense on those all-time deep days.
