Form Function Slingshot STP Harness

For the cost, I do not feel it worth it. When it came, it already had strings from the elastic that I needed to trim. After a few wearings, the second hole through which the scrotum passes through had ripped and widened. The quality of the materials used is just very poor. I bought it to use with the Form Function STP. I am currently looking at other products to replace it.

This is technically for an STP, I use it for just a plain packer (the Pierre). I feed the shaft through the top hole of the harness, similar to the how to use directions for an STP, and it holds the packer well. It holds the position on your body quite well also. The thing that took me a while to figure out is that you wear this harness like a G-string. I actually really like that on a sensory level because "boy" underwear feels like nothing

I use this with a size small Pierre packer and find it reasonably comfortable and very secure. I usually put the packer in a Joey pouch or modified sock to keep the back of the Pierre from directly touching my skin, since no amount of cornstarch powdering seems to keep it from pulling uncomfortably. But about the harness: what I got is made entirely out of elastic strap material, not like the picture where it has a fabric piece and an o-ring. Instead I have a horizontal gap between two elastic pieces to thread the shaft through. Not sure if it will eventually saw away at the base of the shaft but for now it's fine.

Getting this harness for my STP is going to be a game changer. Once you get the STP placed properly in the strap, it sits and holds exactly where it is supposed to, making it much more natural looking. Thank you for the great products. They all help make the transition process so much easier.

I’m still learning how to properly pack, especially with an STP as they’re a bit trickier. But the harness has definitely helped keep it in a more comfortable place and been convenient when I need to use it quickly!
