I think arc'teryx makes good stuff, but its very expensive (for me) and I've never needed anything like that while climbing in the cascades.
I have a cheap ($80) Northface "Hyvent" shell that I use (rarely) all over the cascades, winter or summer. Most of the time, a hard-shell jacket is just too warm while climbing.
It keeps snow off of me allright, as well as anything else. And if it's raining, I'm going home. If it's windy, most soft-shells are windproof, and breath way better.
I dunno, I guess people will prob disagree with me, and i'm sure it's a nice jacket, but I use a much cheaper one and I've never had a problem.
What do you want from your shell? Water protection? Wind protection?
