FWIW, I wear UA heat gear compression leggings and wore the NB "Mongo" and the NB jock strap on the outside of the UA this season. Honestly, OI had no issues and frankly, before, during, and after the games, I had forgotten I even had it on and didn't realize it until I got home! I was very impressed with the comfort. PS . . . hope they make a "John Holmes" size soon . . . :-)
