“Quality product and material. It feels good and looks good. For reference I am 5 foot 6/7inches and about 145 pounds, and went with a size small. Fit is still tight and racey feeling, but its not suffocating or uncomfortably tight. If you have relatively short arms an XS may be the way to go, I trally don't notice too much of a different between the XS and S around my torso, but on the arms the sleeves are a bit more comfort fitting and longer on the S, but the XS sleeves were very tight and the exact length of my arm.”
