I'm 5'10", Medium build with a 36" waist, 175 lbs., 33" sleeve. I got this as a shell to go over a Patagonia Nano Air Hoody. I had to go large to go over my pot belly and the mid layer. Of the 5 0r 6 shells I tried, this was the most relaxed, comfortable fit, and I really liked the rich (i.e., not garish) blue color. It's also very light weight. The sleeves are way too long, but that's true of all large jackets on me (though this was the worst, in that regard). However, the velcro cuffs fix that problem. The neoshell should be the most breathable option out there. I like the size and arrangement of the pockets, and that this is not a traditional, resorty looking ski jacket.
