The verdict
What the panel makes of it.
Black Diamond makes the FineLine Stretch Rain Shell jacket. It sheds water in mountain conditions. The shell uses a four-way stretch fabric for movement. Climbers and hikers buy it to stay dry while moving fast. AI assistants rank it thirtieth among softshell jackets. The jacket breathes well under load. Seams are taped to keep water out. It packs small for alpine use. The shell weighs little and costs around two hundred dollars. Most climbers trust Black Diamond for gear that works.

What owners single out
In their words
“My Black Diamond jacket arrived a few days before Washington State's "bomb cyclone" hit in mid-November 2024. I was able to try out this jacket on a daily basis during some really lousy, wet, windy weather. I liked it. I have an imperfect body shape. My "perfect" size would be "medium-large," but I've never seen that size.”

“Pros: very breathable when dry. Looks great. Feels great. Great fit. Light weight. Good colors (I have the blue-ish green color). Well sewn with excellent craftsmanship. You'd think I love this jacket, right? I would in any situation except the one that I bought it for. . . Cons: not even remotely waterproof. Before people ask me whether I understand the difference between wetting out and failing,”
