This STP Jock Underwear was developed by request for use with stand to pee devices. It features a sewn "O" front that will hold your shaft in place with a split interior for easy access to your equipment. Our jocks feature super soft satin waistbands and breathable cotton blend fabrics that are sure to please.

TIP: If you need a smaller hole for a smaller shaft, simply use a needle & thread to sew the "O" opening to desired size.
