Cake Bandit STP Briefs

by TG Supply

Cake Bandit's STP Briefs feature a 3-layer design that allows the wearer to use a stand-to-pee device safely. While they are designed specifically for use with the  STP Freely, these briefs can also be used with many other STPs, soft packers, and pack-and-play prosthetics.


Construction Details: Our STP underwear has a 3-layer construction.
The inside layer has a slit that acts as a barrier between your body and your STP device when it is not in use. Simply tuck the cup of your STP into the slit to give your junk some breathing room.

The middle layer has a reinforced round hole through which you can pull the shaft of your STP device. Once pulled through the hole, position the head and shaft of your STP in a downward position.

The outer layer of these briefs has an opening with 2 buttons. This layer keeps your STP hidden from view when you're changing or just lounging in your underwear. When you're ready to use your STP, unbutton this layer, pull the shaft out, and take your aim.

STP packing boxers

I really like the stp boxers because of the fit. They feel super comfortable and true to size, so there’s no need to size up. They hold your junk in place really good and make it look very natural. The fly is good for when you have to use the bathroom or when it’s time to do the deed. Overall, they’re really good underwear and I recommend getting them.

Best STP underwear on the market

These are legit the best that are out there. They work well in terms of placement and pack super nice. They tend to be a bit big though so go a size down if youre in between.
