Columbia Back Up™ Beat Pant 2012: Busting out some fly moves on the mountain is no problem, thanks to the extreme mobility offered by the Back Up Beat Pant. Crafted with clean lines and mechanical stretch twill fabric, youll have all the mobility you need to tackle moguls and more. Warmth and weather protection come standard with Omni-Heat® thermal insulation and fully seam-sealed waterproof construction. Our new Back Up™ waist rides higher in the back to keep snow from sneaking down your pants should you take a spill; adjustable tabs at the waist provide a custom fit. When things heat up on the slopes, leg zips at the thighs let you dump extra body heat. Down at the cuff, an elastic gaiter snaps easily over boots or bindings, while a reinforced cuff guard provides great durability season after season.
