STP Freely

by TG Supply


Transguy Supply's signature stand-to-pee device. 

We spent countless hours researching and testing STPs in order to design a device that was attractive, functional, and affordable. Sturdy enough to hold its shape when you're using it, but soft enough to pack comfortably all day long. The STP Freely is never sticky, even after washing, and will never need powdering.

Great first packer and STP

This was my first packer *and* my first STP, all in one go.

As an STP, it works great. I really enjoy the product and it's exactly as I expected, with no problems at all. I was a little concerned because I read reviews from other buyers around my height (5'2), who said it didn't fit their body size properly, but I didn't have any issue. The only accidents I've had are with my own adjustments (shifting it out of place by accident and such).

As a packer, it's a big noticeable, but not to an extent where it's a problem. With ninety percent of my pants, it's perfectly fine, the other ten percent would just be because the fabric is tighter. It was a little uncomfortable at first, but I think that's just because I was getting used to the feeling of it.

I've had no issues that were directly the STP Freely's fault and it's a great product. Highly recommend.

STP Freely

I love this STP! Thinking of upgrading to the XL version. I have been able to use this daily at work. I'm a warehouse worker for a major shipping company and the men's restrooms usually only have one stall and one urinal. Before the STP Freely I had to wait for the one stall to be available now I don't have to. If you haven't had an STP before I think this one would make for a great first. It's comfortable and packs very well.

It has not arrived yet. Is on the way.

STP freely

Love this STP! Works really well with the cake bandit harness (which is the best harness I have ever used thus far). The STP is comfortable and easy to pack with, making trips to the public bathrooms a little less nerve racking!
