Sport STP - 4"

by Number One Laboratories


The SPORT is Number One Laboratory's compact version of the Model D with the same shaft and head. 

The small balls on the SPORT eliminate much of the bulk of a standard STP. The SPORT also has a shorter and less bulky receptacle cup which may take a little more practice for some.

The SPORT has a powder-soft finish. The outer silicone 'skin' has a clean, soft matte texture. Designed to help reduce chafing and remove tacky silicone feel.

- Shaft Length: 4" - 10.1 cm.
- Width: 1.25" - 3.2 cm.
- Height (from below balls to top of shaft): 3.5" - 8.9 cm

It worked amazing

Leif Finn W.
Pretty good

It looks great and feels great on me but the pee function takes practice and kinda hard to keep doing it consistently without peeing on myself it’s kinda lucky to get it just right but it’s pretty good

Chesa Garlough

The product works well and is made well only issue is it’s smaller than I expected the cup to be and the shaft could be a little longer to make it easier to aim and also pull out of pants ect. Overall good product.

Chafing and rash

The overall STP is amazing but there is some cons to it. I was wearing the slingshot harness and the harness gave me a horrible rash on my hip. When I peed I would have to pee very slow. I also felt like I couldn’t really run or do physical activity because it felt like it would fall. This is a okay first STP. Also this gave me really bad chafing around where the cup is. I used corn starch and it still felt really red and rashed. I would not recommend this and going for the more expensive ones.
