6’ 175lbs, athletic build, size M. The shirt has the PERFECT length. It will stay tucked in, or looks good with the casual untuck. When you lift your arms up, it stays below your belt. When you bend over, it won’t make you a plumber. It’s not skin tight, but not excessively baggy. My one critique to the company is to tighten up the arm holes, and shorten them. Unless you have massive biceps, this won’t be snug. A couple rolls of the sleeve solves the problem. This is the PERFECT summer/golf/outdoors polo because it’s so breathable. I need it to be fine when I get sweaty and it is. It will not keep you warm. But it should keep you cool. The fabric is SUPER stretchy. That seems like a big benefit, but if you want to get it tailored at all, I doubt they’d work with this material. I’m hoping it shrinks a smidge in the wash, but I’m not betting on it. You absolutely can’t beat the price either. Going to order more colors.
