You're a professional...something or other. (We'll take your word for it.) Add our All-Pro hat to that "uniform" of yours: its mesh back is specially formulated to keep you cool under pressure – or, um, just looking cool – while the heritage logo at the front panel is clean and classic. Features: 63% Polyester, 34% cotton, 3% spandex. Mesh back fitted hat with inner elastic band for added stretch. Pre-curved brim with contrast underside. PUMA No. 1 Logo at center front. Woven PUMA Cat Logo label at back. Need help figuring out your size? If you wear a fitted hat between the sizes of 6 7/8 and 7 1/4, choose S/M. If your fitted hat size falls between 7 1/4 and 7 5/8, we'd suggest L/XL.
