I am a 43 year old, 5'11' 210lbs with an athletic build. I was concerned these were going to run small or be too tight but they're perfect. Fits as expected. I usually wear large Tee shirts, polos and dress shirts. A typical large shirt (e.g. Fresh Clean tees, Next Level Apparel tees - my favorites - but also Haines / FotL etc) fits me fairly snugly but isn't absurdly tight (no Smedium). I like it snug in the chest and arms and these polos are perfect. I have not washed them yet so I will update with any shrinkage but so far I like the fit.
