I bought these for sun and skin protection for our teenage son to wear on the boat and on the inflatable. I bought a large, thinking a medium would be too snug. They're a little big on him. A medium probably would have fit perfectly. He's long waisted, about 5'9鈥?5'10鈥?55 lbs, lean, and muscular. They are a loose fit, but the length was good, and the sleeve-length left a couple inches for growing room.The shirts helped prevent sunburn and scratching from the inflatable tube behind the boat. I can't say anything about moisture wicking yet., but will try to remember to update when he wears them for that purpose.
