Anyone with sizing questions should check out this page: https://www.weargustin.com/fitguide. They recommend measuring your best-fitting pair of jeans and getting something similarly sized. I did that and everything turned out almost perfectly, though the regulars are very snug on my hard-to-fit thighs. The inseam is much longer than anything else I own (it takes 3 rolls instead of 2.) Also, the belt loops are gigantic - I could wear both my 32mm dress belts at once.
The workmanship, hardware and details are stunning. The fabric on the Super Heavy is amazing, and I expect the Black 2 will grow on me. I find that the stitching (which is the classic orange/tan color) stands out a lot more than I expected it to, particularly on the black denim.
