Does this shell work for backcountry skiing? It seems to be more of a rain shell. Is that true?

Both Ian M. and MC are correct, the Storm is a great backcountry ski shell (which is how I use mine). However, you might also want to take a look at the Nano-Storm. This is another Pat product that combines the Torrentshell (water/wind proof shell) with the Nano-puff jacket (60g Primaloft insulation). In all, it is another 40 dollars, which may or may not be worth it... this will depend on the kind climates you plan on trekking into, and how many layers you like to pack. Both are excellent choices for a cold weather backcountry adventure (or catching a taxi in the rain).

It will work great as a backcountry skiing jacket. The material is durable and will hold up to any scrapes by branches. The only downside is it doesn't have a snow shield around the waste like most ski jackets. If you can live without that though, it'll work great

The Storm jacket can be used for backcountry skiing. It'll stand up to the rigor and abuse!
