Cake Bandit STP 3" Boxer Briefs - New Logo

Cake Bandit STP 3" Boxer Briefs

Built around a three-layer front panel with a built-in STP sleeve, these boxer briefs hold your stand-to-pee device securely in place and ready to go, no shifting, no fumbling, just reliable access whenever you need it. A two-button fly on the outer layer makes getting there fast and simple.

The cut is low-rise with a 3" inseam, so there's no extra fabric bunching under your pants, just a slim, clean line. Not using an STP today? The front panel is built to lay completely flat, so it looks and feels just as smooth and natural without one.

Compatible with the TGS STP Freely, STP Freely Uncut, and The Lou STP, plus most standard flexible STP devices and soft packers, including the My Buddy 4" & 5" Silicone Packers.

Size Guide & How to Measure

Cake Bandit uses standard U.S. sizing based on your waist measurement. These briefs are low-rise and sit on your hips, but sizing still runs off the waist, not the hip. Between sizes? Size up. The front panel needs room to hold your STP device securely.

Size	Waist (inches)	Fit Tip
S	27"–31"	Snug, secure hold
M	32"–36"	If on the larger side of M, try L
L	36"–38"	N/A
XL	38"–42"	N/A
2XL	42"–47"	N/A
3XL	48"–52"	N/A

How to measure:

1. Stand naturally, feet together
2. Wrap a soft measuring tape around your natural waist, where you'd normally wear a waistband, not around the hips even though the fit sits low
3. Keep the tape level and snug, not tight or compressing
4. If you can, have someone else measure for the most accurate read

Care Guide

• 95% cotton, 5% spandex
• Wash cold with like colors and avoid bleach
• Tumble dry low or lay flat; heat breaks down elasticity faster
• Rotate between two or more pairs to extend the life of each
