What Our Gearhead(R) 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.
