I've been rocking my Graphite Navy Insulated Torrentshell for skiing of late, and it has been pretty sweet. I've had H2NO jackets for many years, and have definitely put them through their paces in snowstorms, and light rain. Overall, I'm very happy with this jacket - color, storm sealed zippers, insulation, pockets (including inside pocket for ski goggles).
Drawbacks: I would say that this jacket is not exactly ski specific - no powder skirt and the hood doesn't fit my helmet. Also, this jacket (purchased medium) is quite snug for me as I layer underneath, whereas I wear smalls in my other Patagonia gear (my shells/ski jackets typically mediums - I'm 5ft 7in and have 31 waist). So, if you layer (e.g. fleece jacket underneath), you may want to size up. Also, there are no pit zips, which I'm fine with at this point.
Final thoughts: Great jacket with durable fabric (great for snow and light rain), and proven insulation, but some caveats that may matter depending on end use.
