Product is authentic and great but one word of advice. The sizing runs a little large. These hats have an elastic “snap back” fitting protocol so I ordered what I normally get which is a M/L rather than the S/M. Normally these caps fit me such that I barely need the elastic snap back. This one fit a little looser (kind of like a fitted cap that doesn’t need elastic). For reference purposes, I wear a 7 3/8 cap.
