If you were about 188 and 80 kilos would you have sized up to a large? There seems to be a bit of room in yours left?
Although I don't know what hc is wearing under the coat, I'm guessing it's lightweight. More layers such as you'd wear in spring or fall would take up more space. Also, I suspect hc has not yet washed his coat. Based on my shirt washing experience (see OP), this item will lose an inch or more in the chest when washed, just as the fabric care label advises.
The sale is now on sufu as well. Prices are the same; to do otherwise would be shady. My rep power there is currently very low, as I never posted there before yesterday., so if y'all who are on sufu could add to it, I'd be grateful.
Good news! I now have one more pair of these! 38 (tagged size) waist 32, outseam 45.5, inseam 35, rise 11, back rise 15.5, thigh 23, knee 20, leg opening 16. ONE PAIR LEFT! Retail is approx 210. My price: $50.
