Mammut Stoney HS Hooded Jacket Review: The Ski Shell I Wear All Winter

My new Moss colorway in the Stoney HS Hooded Jacket.

The Stoney HS Hooded Jacket has been in my rotation for years. I used an older version in orange—or tangerine, I can’t remember the exact color name—for multiple seasons, and now I’m in the newer Moss colorway in a Medium. The updates are noticeable, mostly in fit and material feel. Still, the jacket’s overall identity remains the same: a well-crafted waterproof shell built for cold, snowy mountain days with a clean look and reliable performance.

Why the Stoney HS Hooded Jacket Works on Snow Days

The Stoney HS sits in that middle ground between a lightweight shell and a heavy winter jacket. It’s built for people who want a dependable outer layer for skiing on storm days, colder temperatures, and variable snow conditions—without adding insulation or bulk. You pick your layers underneath; the Stoney HS handles the weather on top.

What stands out:

  • Excellent protection in snow and wind

  • Durable outer fabric without stiffness

  • Longer hem for added coverage

  • Pockets that work well with packs and chairlifts

  • Helmet-compatible hood

  • Reliable performance in changing winter conditions

It’s the kind of jacket you can put on and trust for the day.


Stoney HS Hooded Jacket Fit & Sizing

The Moss Medium fits great—true to size with enough room for a midlayer or light puffy underneath. I love the color too. I was eyeing this color last year, and when they had their Black Friday sale, I made the purchase.

The cut has a slightly tailored shape through the torso but still moves well. After wearing both a Large (older version) and a Medium (current version), the difference is clear:

  • The Medium offers a clean fit through the upper body

  • The hem tapers slightly, so sizing up helps if you want more room through the hips or plan to layer heavily

In short:
True to size, but consider sizing up for extra hem room or bulkier midlayers.

What I Like

  • Durable fabric with a smooth feel

  • Hood that actually works with a helmet

  • Zippers that stay smooth even in ice and snow

  • Plenty of venting options when things heat up

  • Enough room to layer without feeling bulky

  • Reliable in stormy, snowy weather

  • Updated fit feels cleaner than older versions


What I’d Change

  • Slight taper at the hem means some people will prefer sizing up

  • Not ultralight—this jacket prioritizes durability

  • Seasonal colors rotate quickly


Who Does This Jacket Fit Best

This jacket is a strong match for people who:

  • Ski in cold, snowy climates

  • Want a durable shell that blocks wind and snow

  • Prefer choosing their own insulation layers

  • Need a hood that fits over a helmet

  • Like longer coverage at the waist and hips

If your winter system is base layer → midlayer → shell, this jacket fits perfectly.
