Men's waterproof rain pants built for fast-and-light mountain pursuits, the Black Diamond Fineline Stretch FZ Pants combine a 2.5-layer BD.dry™ membrane with a stretch nylon face fabric to deliver reliable protection and unrestricted mobility in wet conditions. Fully taped seams and a PFC-free DWR finish keep you dry, while full-length side zippers allow quick on-and-off over boots or harnesses.
