I normally wear a small in normal Adidas tops and medium in Adidas golf polos. I sized up to a large because I wanted it a bit loose so as to not affect my swing. The shoulder area actually fits perfectly. It would have been tight if I had bought my normal size. This is a thinner material than my other Adidas golf polos so it’s perfect on hot days. Lengthwise, it’s long enough for me to tuck into my pants so it’s perfect.

great fit and looks really smart. feels nice on too.
