STP COMPATIBLE

Ready for your STP, fine without one.

Every Cake Bandit STP style is flat front, so it works with an STP, a soft or hard packer, or nothing at all. Want one piece that does it all? Get STP underwear. Love your own underwear? Add an O-ring harness or the pin-on STP Packing Pouch.

Everything here works with an STP or a packer.

All our house STPs, the STP Freely, STP Freely XL, and Lou, work with O-ring harnesses. The key is lining up your urethra with the STP's opening. The STP guide covers positioning in detail.

Cake Bandit sits low, on your hips, not your waist. Measure around the widest part of your hips and seat. Between sizes? Size down if you like a snug fit or pack heavy.
