This jacket has surpassed my expectations. It's very high quality, fits well and looks good. Functionality is great, lots of pocket, pit zips, snow skirt you name it. Nothing missing. I've used this jacket for low intensity ski touring and resort skiing. It's warm enough and works with layering. This is now my go-to jacket for resort skiing and light aerobic winter activity.
This jacket crushes it on the mountain. Super comfortable, great fit, and it looks clean—but what really sold me is how it handles nasty weather. I’ve ridden in rain, sleet, and brutal wind and stayed totally warm and dry. I don’t like wearing a bunch of layers, so the insulated (down) version is perfect—it keeps me warm no matter the conditions. The pockets are also super well-designed—plenty of space and easy to access everything I need without digging around. Easily my go-to jacket for any day on the hill.
I purchased this to go back country skiing and in bounds skiing this past season. I loved it. It is light, somewhat packable, and has great waterproofing qualities. The thing I would improve would be the packability of it in a backpack when the day gets warm.
High quality construction and toatally waterproof. The down version is great because it gives you extra warmth in peak season and you can unzip the vents in early and late season
This jacket fits great and is well designed. It kept me warm and dry when the snow ended up being rain for the day.
Best jacket I have had. Warm and not too bulky or big. Vents make it great for warmer conditions as well.
I really like the fit and warmth of this jacket. It is a great ski jacket for all weather.
