Black Diamond Fineline Stretch Shell Men's Waterproof Jacket - Black

A featherlight, stretchy waterproof shell built for fast-paced mountain movement, the Black Diamond Fineline Stretch Shell delivers 20,000 mm of waterproof protection with equal breathability. Its BD.dry™ 2.5L fabric and athletic fit keep you dry and unrestricted on climbs, scrambles, and alpine routes.

Advantages

The Fineline Stretch Shell pairs a supple nylon stretch woven face with a PFC-free DWR treatment, shedding rain and snow while allowing dynamic reach. Fully taped seams and a YKK AquaGuard® zipper seal out moisture, while the helmet-compatible hood adjusts for full coverage. When the weather clears, the jacket packs into its chest pocket and clips to your harness with the integrated carabiner loop.

Suitable for

• Climbing and mountaineering in wet, windy conditions
