(Packer + STP) Jock Harness X-LARGE 39-41


The Jock harness features an "O" stitched front that will keep your prosthesis in place with a split interior for easy insertion and open back that allows "easy access"..  This jock was also developed to be used as an STP sport jock for stand to pee devices (not designed for flexible packaging).

Perfect for those who want light support.

(Not compatible with SP1 / SP2 / SP4 / SP6 / SP7)

+ Front sewn in "O"

+ Divided interior (folding)

+ Quick-drying fabric

- Cold wash, gentle spin. Hang to dry

Note: The O-ring is not silicone - the stitched "O" fabric easily stretches to fit most hard play prosthetics / STP devices.


Innovative products adapted to meet the needs of trans people and other genders.


We are a small company that makes each prosthesis by hand.


Our products are designed with the highest quality of certified silicone.

Amazing !

At first I was feeling a little tight, I am normally putting on boxers. But after putting on my prothesis, WOW ! Everything is right where it belongs and it is ultra confortable with so much support. LOVE IT !

I am obsessed!

This is the best STP jockstrap and is worth every penny! It is the first daily wear harness I e found that holds things exactly where they need to go! I am obsessed with it and will be getting more! I am usually an XL kind of person and I got the L/XL and its good.
