July 24, 2025Every product I review has been thoroughly tested—on the mountain, in various conditions, and across multiple seasons. Whether I’m skiing powder in Utah or navigating icy, hard-packed terrain in the Midwest, I only share gear that I use. I care about performance, durability, and how something’s built—not just hype or trends. I’m skiing on Black Crows because they work for me. That’s the only reason they’re in this review.
Why I Picked the Mammut Stoney HS Pants
I had a pair of the Stoney but I needed a size change—down, thankfully. The reason I’m reviewing this newer pair is that the updated design is even better. It fits better and is more comfortable on the slopes.
If you're a cyclist, Mammut reminds me of Rapha. The material and fit just feel right on. And that’s why I keep coming back. There’s a reason this is their best-selling ski pant. They’re warm, breathable, and move well without feeling bulky. I ski in a mix of conditions—Midwest ice, Colorado powder, and everything in between. I ordered the Stoney HS pants in black, as always, and after wearing them on one trip, I knew they were staying in my kit.
Fit, Sizing, and Movement on the Slopes
Right out of the box, they felt like quality. The waistband adjusts easily, and the cut is flattering but functional. I didn’t have to fight the fabric to move. They're roomy enough to layer underneath but don’t feel oversized.
You can order short or long lengths—I ordered the short this time. I had the long version before and it felt a bit sloppy in the length. I'm 5'5", and the short fits just right, even over ski boots. No bunching or stiffness at the knees when you're skiing—they’re cut to move with you.

Final Take
These are the ski pants I keep reaching for—warm, breathable, and made to move. If you’re looking for a pair that handles cold, wind, and slushy days without feeling bulky or stiff, the Stoney HS pants check every box.
They’re not the cheapest, but they’re built to last. I’d buy them again. If you want something warm and functional that doesn’t scream tech or trend, the Stoney HS pants hit a sweet spot. They're comfortable, built well, and ready for whatever ski day you’ve got lined up.
