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.

If you are looking for a packing jock with no "O" opening to use with your soft packer, click here.

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

MATERIALS & CARE:
- 95% cotton, 5% spandex.
- Machine wash cold, tumble dry low.
- Note: O-ring is not included in underwear.
