I use this jacket in the PNW where we get more snow and rain and wind and so forth in a weekend than Colorado gets in a season (ok maybe not, except for the rain part).
Anyways, the Cosmic is my favorite of the TREW jackets. I'm a fan of cleaner, lighter jackets and this one fits the bill w/o making me feel like an extremo French alpinist. It's got all the alpine techy features you want and a fit that's freeride-y, but not ridiculous like the "I'm 5'6" but I wear XXXXXL with a cotton skirt hanging out" style that seems to be all the rage with kids these days. The fabric is tough - if you see a scuff on it you should see the splinters or sand left over from the tree or rock I just cartwheeled over and see who won that battle.
BTW, I am 5'10" 160# and wear a L.
