Fineline Stretch Full-Zip Pant offers lightweight waterproof protection with full mobility for mountain adventures

What Our Gearhead® Experts Are Saying:


“These are my go-to rain pants when I need fast coverage without slowing down. The full side zips make them super easy to throw on over boots or harness, and the BD.dry fabric is lightweight yet protective. They pack into their own pocket, so I can stash them in my pack and forget about them until the storm rolls in.”


When the weather shifts from bluebird to stormy, the Black Diamond Fineline Stretch Full-Zip Pant is the emergency shell we’re glad to have tucked away. Built with BD.dry 2.5-layer fabric, it delivers waterproof, windproof, and breathable protection without unnecessary bulk. The articulated knees and two-way stretch design mean we can scramble, hike, or climb without feeling restricted, while full-length side zippers let us pull them on quickly over boots or layers. Once the clouds clear, they pack down into their own rear pocket, taking up minimal space in our kit.

Great Rain Pants

Size up to be comfortable over regular pants. Great lightweight and simple material that will keep you dry. Could use a better waist strap.

Awesome pants

Great features, very waterproof, and super durable. Only complaint is length, returned this pair and opted for a women’s xl for the shorter inseam. Adding different inseam lengths to the size ranges would be awesome.

light weight, versatile rain pants for BC skiing.

Essential side zip, tear away style lets you don and ditch the layer while wearing skis, boots or standing in puddles. Highly waterproof, mildly breathable. Stows unnoticeably in my pack stuffed i side its own pocket. the ultra lightweight nature of the fabric seems less durable, but time will truly tell. The bit of stretch is enhanced by the technical cut making mobility excellent. The cinchable drawstring waistband has limited sizeability range. Over bulky knee pads, I use suspenders to keep XL up on my L-sized frame. I have enjoyed wearing them spring telemark skiing.

Waterproof and light

I found excellent the relation between weight and water resistant, and easy to put on and off with the full zipper. I'm happy with this pants

Quite Possibly the Perfect Rainpant

I can't give the full 5, only because I haven't beat on them enough to assess the durability, but. . . These are obviously a very well thought out design. Relaxed cut, but not frumpy, with enough stretch to accommodate any activity. For me, full length zips are a non-negotiable on a rain pant, check, plus 2-way operation for venting and pocket access. A generous seat pocket for incidentals, fits a smartphone no problem, and cinches at the waist and hems. If I could change anything, It might be to replace the zipper cover snaps with hook-and-loop. While secure, they are a bit stiff and seem to really torque the fabric before releasing. Add a little trail grit and cold fingers, and you get the picture. Feels good to finally check that rainpant box on my kit list.

Perfect pants but wish there were more size options for length.

The material is great but I wish there were more sizing options in terms of length like a short, regular, long option.

Perfect foil against "wintery mix"

Packs away to nothing, easily added on when the weather changes. Effective protection in snow/rain transitions during work or play in the mountains.
