Why We Like the Stoney HS Thermo Jacket

Mammut's Stoney HS Thermo is a solid ski jacket that keeps us out whether it's powdery or brisk and bluebird. We appreciate the body-mapped synthetic insulation and superior waterproofing for winter's weather, and the hood and powder skirt are removable for sunny groomer conditions.

Comfy, great for the hill. Been looking for a new ski jacket for a long time, this was a great find. Handles the winters like a champ.

Awesome Ski Jacket!

I needed a new insulated ski jacket & this is the best so far. It is great for free skiing on a cold day, very warm & comfortable. It will be great for ski racing, to wear over my speed suit to stay warm at the start. I really like the pocket locations & nice pit zips. The detachable hood is great & fits over a ski race helmet good. I am glad I got size large, I am 5'9, 165 & usually get a medium. The shoulders & chest fit perfect, with room for some layers under. The sleeves are a bit long, but I can live with that as the only negative. Overall it's great!

I bought my 10 year old daughter a previous year of this jacket and loved how packed with features it was. I typically ski with a shell and layered insulation, not with an insulated jacket. As we were hitting some negative temp days I decided to give an insulated jacket a go again and ordered this Mammut. I have been extremely happy. It looks great, has a ton of features, and is a great step up in warmth for me. When I miscalculated and wore it on some warmer days the massive pit zips were great. Overall I think it's great!

Good for the north east

Great jacket for the constantly changing weather of the north east. After hours of rain at a Bills game that later dropped near freezing and I stayed dry and at a reasonable temperature.

Perfect amount of insulation

Love this jacket! Pockets are great, level of insulation is perfect for inbounds skiing. Just wore this jacket three different days skiing in Colorado and Utah with just a heavy base layer for all day skiing and it was perfect. Temps were in the 20's and low 30's so might have worn a vest as well if the temps were lower. Quality looks and feels great.

Excellent product although I haven't tested it yet in cold conditions, like Jackson Hole, WY. Fit is a little big, but you need room for layering. Seams look well taped and zippers look great. Color and design is excellent.

Great Jacket!

10! I love the collar in snow storms. Perfectly sized to give me breathing room and keep snow off my neck. The zippers are fantastic. The pulls are large enough to grab with my gloves on and are water and airtight. In a wicked Colorado blizzard I was the driest person on the last chair. The slim fit of the jacket also keeps snow from piling when I'm not in motion. Perfect jacket for storms and cold.

Great Jacket. However it is too warm for me. I burn up when temps are in the teens and need to shed layers. This jacket is just too warm for me. I returned it and bought the 'non thermo' HS stoney
