Waterproof. Breathability. Durability. Our 2.5L jackets are made up of three parts: a face fabric treated with a DWR without intentionally added PFAS finish that sheds water; a microporous membrane that goes on the inside and stops percipitation from penetrating; and a half layer print that goes on the inside of the membrane, right next to your skin keeping it dry and comfortable. BD.dry 2.5L Waterproof rating: 10,00mm Breathability rating: 10,000 g/m2/24h

"Used these pants during a Mt. Rainier mountaineering training where we were in the snow a lot. These pants kept me completely try. The full zip is amazing for putting on when wearing crampons. These were excellent."
"Awesome for going the distance in hot, long touring days!!"
"confused for the Waterproof rating: 10,00mm, the essential piece missed,aembarrassed!"
"Well built rain pant by inspection, although not yet field tested. Zippers work well. Buy one size up if you plan to wear over pants, that seemed to work well for me on sizing. The stretch material is a great feature for mobility"
"I work outside 10-12 hours a day. I finally got tired of suffering through the rain and bought these. Most rain gear I’ve tried makes you sweat so much it’s pointless to wear it. Not a problem with these pants. Easy on and off with full length leg zips, which also means easy venting to prevent trapped body heat from making you sweat. Fabric is sturdy and durable, minor scrapes that would rip gashes in normal rain gear don’t phase these pants. Overall best purchase I made in 2025 to make life easier on the daily grind."
"The fit is quite slim, which makes it difficult to layer over other pants. The zippers can be finicky to use. They soaked through the first time they were worn in steady rain, and the fabric doesn’t feel very durable. I sliced them with a crampon after a light brush."
"Can’t wait to try them out, look like good quality. I wish they had belt loops, drawstring to tighten around the waist, or suspenders. I hope they stay up when in action. I think they will. They look nice and breathability is key!"
"I like the full length zipper and their packability. I haven’t used a rain jacket made out of the same material and it keeps me dry. I expect these will work just as well."
"Killer pant to have in the quiver. Full side zips are easy to use when you need them most"
"My husband liked it very much, nice slim look and move comfortably."
