The American Jock AJ Mesh Collection is designed for guys who favor the classic jock, men's bikini brief and men's boxer brief trunk style but with a modern twist. The front pouch and backside (except the jock) are constructed in semi-transparent sport mesh for an airy and athletic look to keep you cool and comfortable. Short side seams along with contrast stitching outline your best attributes in the bikini and boxer brief trunk. 90% cotton 10% Lycra. Made in U.S.A. Los Angeles, CA.
