They are of good quality - significantly thicker than many Hanes undershirts. I usually wear medium sized clothes (5ft 10", slim build), but these shirts are a bit long for me, both in the sleeves and upper body. The sleeves can stand out if you wear these shirts with a short sleeve shirt over them. And they can stick out from underneath if you don't refuel them (which I usually prefer not to). Hope this is helpful!
