Definitely go to a local store and at least try on something from OAKLEY to get the right fit (if that's the brand you want). I made the mistake of buying a Burton coat last year online and the arms were a little short. Gloves kept popping out of the sleeves = SUX. Not to mention it was as basic as a coat could get. I wasn't impressed.
I tried on a Quicksilver a few years back and it was insane. It was also ~$300 so I passed, but def seemed worth it for the technology in it and the comfort. I wish i knew what model it was...
Anyway, DEFINITELY try on the coat before you buy if possible. You'll be much happier.
