This utility coat is a bit more hardcore than the other one – it has less clean lines and more seams and elastics and whatnot. Most notably, it seems to have elastic at the top of the breast pockets, and a thick seam running from the neck to the top of the breast pocket. It has large grey buttons. (Note: this coat is actually green, but the filters on the cameras consistently make it look grey, so I've just kept with that colour description.)
Brand Information: This is a Commander Slub Twill jacket made by GAP.
