Thanks for the help, y'all. I do like the Arcteryx shells; They fit great!
So a slight change of plans, and a bit of an epiphany. So while cleaning-out some snowmachine accessories, my wife found her neon blue/pink Columbia snowsuit. This had only been worn a few times, c.2000, so it is tip-top. And a Mens Medium! She was going to donate it, so I swooped-in to stop that madness.
I now have several days on the hill with this bad boy, and all I can think of is; What the hell have I been missing all these years?!?! Warm, snow and wind will never get in, and unimaginably practical, compared to separates. Hook. Line. Sinker.
The catch is that the long-suffering won't be caught dead skiing with me, with this beauty on. Who makes new (ski/mountain) snowsuits? I've done a fair amount of searching, and all I can find is one from Spyder. Any ideas?
