Love 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!

It’s a bit loose
Best workout/running/gim jocks ever
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.
