Black Diamond Fineline Stretch Shell Rain Jacket Men's

When clouds roll in and temperatures drop on a committing alpine rock route, the Black Diamond Fineline Stretch Shell keeps you climbing. This men's rain shell is built with BD.dry™ 2.5L technology, delivering 10,000 mm waterproof protection and 10,000 g/m²/24hr breathability in a lightweight, packable package. The 100% nylon face with PFC-free DWR sheds moisture, while fully taped seams ensure no leaks. The climbing-specific slim fit allows full mobility, and the helmet-compatible, single-pull adjustable hood stays secure in wind. A YKK AquaGuard chest pocket stores essentials and doubles as a stuff sack with a carabiner clip loop. Low-profile elastic cuffs and a single-pull hem seal out the elements. Whether you're on a multi-pitch, hiking a ridgeline, or trail running, this shell is your go-to for unpredictable weather.
