Supreme rain jacket!

My favorite light and breathable rain jacket for any hiking. I likely wouldn’t take it mountaineering as the material is incredibly thin/light, but it’s great for any other outdoor activity.

Nice Jacket, But. . .

It seems like a nice jacket, but the fit around my neck is very large. It doesn't seem to be sized that way to fit a climbing helmet or ski helmet. The under-chin area when zipped up sticks out far enough that I am concerned it would catch water, if/when it rains. I really like all the other aspects of this jacket, but that was enough of a deal breaker for me.

After a disappointing experience with

After a disappointing experience with my old rain jacket in Norway, where it failed to withstand, heavy rain, even with a fresh DWR coating, I knew it was time for a new rain jacket. The Black Diamond Fineline Stretch Shell has proven to be a dependable choice. It has performed well in Colorado's unpredictable mountain storms, keeping me dry, even in wind-driven downpours.

Great Fit, Keeps me Dry!!!

The jacket fits great and kept me completely dry during a heavy rain while golfing last week. The flexible, stretchy material made it easy to move without restricting my swing. At 5'10" and slightly overweight, the medium fit me well - snug but comfortable thanks to the stretch. Highly recommend this jacket for anyone who needs full range of motion while staying dry.

Recommended by friends

I haven't had to use it yet, but my old rain coat delaminated and my friends and teammates recommended this one for the Adventure Racing World Championship (10 days of grueling wilderness travel).

Great product

Excellent product. Used it on Mt. Whitney, got rained and snowed on. The shell preformed flawlessly.

Definitely keeps rain out but tight in the arm pits for a more muscular build.
