Cake Bandit STP 3" Boxer Briefs – STP-Compatible Comfort, Confidence & Control

The Updated Cake Bandit STP 3" Boxer Briefs were designed by folks who actually understand what your body needs. Sleek, secure, and built for all-day wear, these briefs combine a 3-inch inseam, low-rise cut, flat front with thin 3 layer panel, and smooth contoured fit that stays put without bunching, rolling, or shifting. The STP-compatible front panel gives you reliable access and stability for your stand-to-pee device, so you can move confidently through every part of your day.

The stp ring was slightly too small for my stp but it’s due to my stp being too big, nothing wrong with the briefs at all. Comfortable and breathable.
