does anyone know if the measurements on the down shirt jacket on the website are accurate (it says chest size of 42 for the XL, which seems like it would mean that it runs small rather than large, which is what i would have guessed.)? also, do the SW sizes differ from the regular CDW pieces that you would buy direct? Just received a parka that I found on ebay, and it's an XL and gigantic. i am going to keep it, as i got it to be a serious outdoor piece for the vermont winters, and it will function as that, but it's huge. want to pick up the down shirt too, just not sure if it will fit (as 42 would be a bit tight). appreciate the help!
