Black Diamond’s waterproof/breathable/windproof solution. BD.dry™ 3L ... Black Diamond’s waterproof/breathable/windproof solution. BD.dry™ 3L face fabrics are treated with a DWR solution without intentionally added PFAS and these fabrics have a hydrophilic membrane that allows water vapor to transfer through, making them waterproof, yet breathable. Applied to the backside of this fabric is a third layer, jersey backer, that feels comfortable next to the skin and allows moisture to turn to vapor before passing through the hydrophilic membrane.

From clean climbing, to conservation, Black Diamond is committed to protecting the people and places we love.
Reviewers praise how dry it keeps them, the breathability and pit zips, the light weight and the build quality, using it for alpine and ice climbing, mountaineering, ski touring, hiking and rainy everyday wear. Most say it fits true to size with room to layer, though the long cut splits reviewers: five like the extra coverage and five found the body or sleeves too long. Most report it staying waterproof, though one had it fail after two to three years and one saw early wet spots.

"I want to start by saying I was a little skeptical to buy past-season at a final sale. It turned out to be a blessing as the jacket fits true to size, and it has excellent waterproofness in rain and snow on multiple hikes I've been on. It looks very nice and can be used as streetwear also, so I would definitely recommend to anyone considering a good hiking/skiing shell, this gets the job done excellently."
"High quality waterproof jacket with a nice fit - 5ft11, 150lb, M fits me perfectly. Very large hood able to accommodate climbing helmet."
"This is the shell I grab most of the time. It’s accompanied me on countless backcountry adventures, kept me warm on top of the Grand Teton, and kept me dry on bike rides around town. The pit zips make it super breathable, so I stay dry from the elements without sweating myself out from the inside."
"Works as a great rain coat, but it’s so much more. Do everything mountain shell without unnecessary extras. Highly waterproof, highly breathable, semipackable, all mountain shell. Can be used as a ski mountaineering shell, or in bounds, as well as a cold weather hiking shell. Extremely versatile. 6’1” 175#, Medium fits with room for appropriate layers. Good to about freezing for low output with a light puffer and base layer, and well below freezing for high output activities."
"I bought a size small and it weighs 15.1 ounce vs 12.7 on the site. On the fit, it is cut oversized - very long length in body and sleeves. I bought small (normally medium) because of this and it was still a bit long for me but a bit too tight on the waist and shoulders for me to make usable. So I would need to get medium but would be swimming in it."
"Used this in multiple trail running races the last few weeks in Colorado! Stayed dry and warm. Looking forward to test it out during the winter"
"Stay away from this product. The water proofing is not working after 2-3 years, even if you reapply Durable Water Repellent (DWR) like Nikwax. I have contacted the support, and they told me it's normal, and won't do anything about it."
"Great jacket, really well made and the materials are high end. I'm 5'8" 155lbs and i got a medium. The small might fit me. The medium is incredibly long and while this might provide more coverage, I'm not certain the extra length is necessary. worn with a harness one can manage the extra by using the draw string and it works well."
"Good build quality and features. Kept my dry, but the fabric appeared to wet-out in a couple spots in the first few uses."
"Took this up some mountains, works well for a hard shell when below freezing. Breathable zippers under the arms is continent when on the hot descend"
