Used a few times for some tail runs, but not more than a handful. It's in near-new condition with no flaws. It's a seamless shirt with not tags and really cuts down on any chaffing. It's a baselayer cut so it fits slim. I'm on the line between large and medium and it's a bit too tight for me. See pics for measurements. It's an awesome shirt. Wish it still fit. Please ask any questions. Thanks!
