S, M, L, XL - Men's polo, made of 5.75 oz. 96% Poly/4% Spandex. We offer 18 colors in this polo because it sells like hotcakes! Lightweight poly that breathes, doesn't snag easily, doesn't wrinkle easily, doesn't fade or shrink, and a collar that never curls. Just enough spandex to stretch a little, but not enough to effect the drape of this shirt. It's as close to a maintenance free shirt as you're likely to get. Made in the USA.
