I've owned this jacket for a few years now and, while I usually go with a multi-level layering approach using my Furio shell, I grab my Stormbound for the bitter cold days on the slopes. This jacket is bomber and like wrapping a 0 degree down sleeping bag around your torso. I find that wearing a base layer tee, my Radiant Hoodie, and the Stormbound keeps me snug and toasty on the coldest, windiest, and wettest chairlift rides. I've had this out on some pretty wet PNW days, and stayed completely dry. The myriad zips allow for ventilation when working hard for turns and the ample pockets keep all my gear stored. The little details are awesome too - Recco integration, pass pocket, zip-out balaclava, removable pow-skirt. This jacket may be too warm at times since the down really does it's job. If I'm skinning in the B/C, again, I'll opt for a more layerable system. But when I need to be warm and dry, the Stormbound delivers.
