Why We Like The Stoney HS Pant

From scoping lines deep in the backcountry to searching for hidden gems at the resort, the Stoney gives us the freedom to find and shred the season's best turns. Mammut's DRYtech Pro material holds its own through rugged conditions and turns away icy gusts and deep powder, all while letting our skin breathe underneath to keep us comfortably dry.

Here's what customers have to say

The product is a high-quality, versatile option for outdoor activities. Key features include excellent waterproofing and breathability, lightweight and flexible material with good insulation, well-placed vents and adjustable waistband for temperature regulation, and durable construction. However, the slim, form-fitting cut may not suit all body types. Reviewers recommend carefully checking the sizing before purchasing.

Great fit!

These pants fit really well. So well that I bought both the insulated and uninsulated Stoney's.

Very waterproof and well vented

I use them for skiing and they did great during some powder days in Alta, UT. Kept me dry and warm with just a layer of compression pants underneath. The side vents are huge for when its warm and easy to open and close with gloves. The zippers keep the water out easily when closed. They are not bulky in any way so I very much prefer them over anything with built-in insulation.

Well made!

Familiarity:
I've used it several times

Love these pants, lots of pockets, belt loops, too! Wish they came in various lengths, just a tad bit too long.

Great for resort skiing

I love these for resort skiing, the waterproofing is excellent. The vents work incredibly well. I am 5’10 170lbs and got the 32 waist and regular length pants and they fit snug around my hips but perfectly for me. If you wear regular pants in a size 32 but you want to be able to layer more and less body hugging I would go a size up. I just wear a thin thermal layer underneath and they’ve been warm enough for mid season skiing in Alaska.

Great slimmer fitting option

Familiarity:
I've used it once or twice and have initial impressions

They fit perfectly, slimmer than some other options. The only slightly strange thing about these is the pockets; they are not all that deep, but large enough for something like a wallet or a smaller phone. As someone else mentioned, there is some light insulation, but that is fine for resort skiing.

great pants

Familiarity:
I've used it several times

These are great ski pants for cold, snowy or wet conditions. Their only shortcoming is that they are on the warm side for a shell pant, because the inside liner (they are 2 layer, not 3 layer) is quite warm. That said, they have excellent outside leg vents, and I run hot, so this will be a non-issue for most folks (and for me, except in the spring). I have worn these in cold and windy and warm and sunny conditions and they have performed admirably. They are very comfortable, fit really well (size S, I am 5’6” and 145lbs) and look great.

Super nice pant, definitely a "Euro" cut

Love the pants, super nice like all Mamut gear with thoughtful features and great materials. But, take heed yee of "athletic" proportions! I'm a thin, skinny-legged 6'2 with the 34 and if I had manly quads there is no way these would fit. Size up. As is, they are great for me but it's *close*.

Very comfy and versatile

Pants fit true to size. I'm a 30 in regular pants and the stoney size 30 fits perfectly. They are a little warmer than other shell pants I have owned in the past. Overall, the most comfortable pants I have ever owned. I would recommend these for resort and bc use. Although, the pants do not come with a built in transceiver attachment. The vents are very useful on the ups, and the extra warmth helps on the downs.

Great Pants

I was able to get a size than fit me well. Many other pants are too long and baggy but the Short fitting is great for me (5'9"). The pants are warm, comfortable and stylish.
