With a 10,000 mm waterproof rating and fully taped seams, the Black Diamond Fineline Stretch FZ Pants keep you dry through the worst downpours. The BD.dry™ 2.5L membrane delivers reliable storm protection without the weight, while the stretch nylon fabric moves with you on steep approaches and technical scrambles.
