This by far has to be my favorite shirt I’ve purchased in some time! It’s 100% polyester and feels super lightweight! It’s nice and breathable. Good to hit the gym with or even just running around taking care of errands. The color is on point and the logos don’t come off as cheap iron on vinyl. Very well constructed! The sleeves are and bit on the long side but not enough to keep me from wanting another! Pics posted with show how the sleeves are! It’s not a complaint in anyway.
