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.
