Great rash guard, fits pretty darn tight. I got the LG size and I'm 5'8 170lbs with about a 40 inch chest. Everybody is built a little different so I guess I can't complain that it seems a little tighter in some corners of my body than in others but overall the fit is good. I also had some threads hanging out the sleeves out of the box but I trimmed them off and have had no problem after many weeks of rolling 3x / week. It feels great to roll in and looks really good. The only weird thing is that for being as tight as it is the sleeves are super long. When I roll the sleeves all the way down they come almost to my finger tips. I can't imagine what the guy looks like who is my size but has arms 5 inches longer than mine. But it's no problem, they just bunch up a bit at my wrists and it hasn't affected my rolling at all. Overall love it. Dries really fast too.
