United StatesLove the fit!
I got this for working out but I use it for almost anything because the material feels great and the fit is perfect. The waistband doesn’t ride up in the back when you wear jeans or shorts which is an issue I have with other brands!

Impressive jock to go to the gym or run into. Holds everything in place and provides a feeling of sexiness at the same time. This is top quality stuff.
