I wear this every day in a retail/warehouse environment. I'm in and outside during rain and cold temps, in and out of freezers and coolers most of the day. I really like the cut and fit. Workmanship seems excellent. I'm 5'11'', about 180 lbs, and I order a large in most things, so I ordered this large as well. It's not tight or loose, but fits well with extra room to move and work, so layering is possible. I don't think a slimmer fit would serve me any better so the large seems right on for me. I look forward to trying more 1620 gear. Thanks!
