Cake Bandit Monochrome 3" STP Boxer Briefs – Sleek, Secure & STP-Ready

The Cake Bandit Monochrome 3" STP Boxer Briefs deliver everything you love about Cake Bandit underwear in a clean, minimalist design - no harness needed, and they offer the affirming functionality your body actually needs.

At the core is a three-layer structured front panel with a two-button fly and built-in STP sleeve that holds your stand-to-pee device securely in place and ready to use. No shifting, no fumbling, no unwanted bulge changes - just reliable support and easy access all day. When you're not packing, the front panel lays completely flat for a smooth, natural silhouette.

The 3-inch inseam and ultra-soft cotton-spandex blend keep things comfortable and flexible from morning to night, whether you're running errands, hitting the gym, working a long shift, or heading out with friends. Sleek, discreet, and totally gender-affirming.

Fits great and works well for STP. My only complaints would be that the legs are pretty short, and that the seams in the legs dig into my skin. Other than that though, I'd recommend these if you need boxer briefs that work with your STP. The one I use is the Packer Gear Ultra Soft Silicone STP in size Small for reference.
