Why We Like The Alpine Pant

The Black Diamond Men's Alpine Pant is a no-frills softshell pant for climbing, touring, or any other cold-weather aerobic activity. Articulated knees and four-way stretch woven fabric combine to create rapid-drying, easy-moving pants ideally suited for action in the backcountry. A water-resistant treatment protects your legs from light rain and snow, while the highly breathable softshell material ensures your legs feel fresh and comfortable all day. An adjustable belt with low-profile buckle allows you to customize your fit, while ankle adjustable cuffs pull over most boots to keep out rocks, ice, and snow.


  • Ideal for long days touring or ice and mixed climbing
  • Just the right warmth for fall and spring missions
  • DWR finish repels light rain and snow
  • Four-way stretch material promotes mobility while climbing
  • Slim fit reduces bulk for a streamlined fit

Pants don’t fit and can’t exchange

I bought these on a Black Friday sale and they didn’t fit. The only option I have is to now buy a larger size at full retail price as there is no exchange option.

Hands down the best pants

Hands down the best pants I’ve ever worn. The 4-way stretch, the breathability, the overall fit…these hit the bullseye.

Classic bangers

About as pragmatic as it comes. Love the leg zipper for stashing quick access items. The fit is athletic without being tight. The light water repellency helps keep the smell of whisky off on pants during the long weeks at the creek.

Great features

This is a well thought out pant. The integrated belt is one of the better ones on the market, and the ankle cinches are handy. Nicely stretchy, good weight material- light enough to not overheat but heavy enough to feel pretty durable

Fit perfectly and has large pockets!

Finally a pair of pants that can fit my tiny 28” waist as a guy with normal length legs.

Great athletic fit, long length, durable fabric, versatile weight/insulation.

Not as warm, durable, or versatile as BD Vertical or Dawn Patrol pants of yesteryear, but a darn good alternative. Fit is much better. I am 5'9 inch waist 33 waist and this pants adjustable waist loop goes from starving-alpine-decent to all-you-can-eat sushi with room to spare. The hem is longer than most other pants I own, so tall guys will appreciate that. For me, it helps keeps the snow/pebbles out. So far, the fabric has been pretty durable. I got another two pair in case BD decided to change sizing or discontinue these pants. The weight/warmth is not great for hot summer or windy-cold summit, other than that it is pretty darn versatile. As a sign note, BD, please adjust your sizing for the Alpine Light pant to resemble these pants. Your Alpine Winter pants are also great for conditions where this pant isn't warm enough.

The only pant I’ll buy for work or mountaineering.

I work in construction and spend my free time in the hills. These pants are both rugged and flexible!

Alpine pants still really good

Got a pair with thicker premium Schoeller Swiss fabric a few years ago - which were also stitched a bit differently (e.g. stitched in back pocket vs free hanging) and a metal latch on the built-in belt vs plastic type now. They were fantastic. The new ones are a bit lighter wt but appear to be made of a similar stretch material. They are also very comfortable. Look to be well stitched, good quality zippers. Would recommend. Good product

Excellent stretch -- perfect for climbing

Fits well, looks nice but most importantly, the stretch makes the pants super comfortable no matter the position.
