STP sleeve built right in.

Clean boxer briefs with a built-in STP sleeve behind a two-button fly, so you can skip the harness.

Details

The sleeve holds your STP in place, and the front lays flat when you're not packing.
A three-layer front panel keeps your STP steady and helps stop leaks, so you're not fumbling at the urinal.
3" inseam in soft 95% cotton, 5% spandex.
Low-rise fit that sits on your hips, with a clean monochrome waistband.
Flat seams that don't rub or roll.

Works with the STP Freely, Freely Uncut, Lou STP, and most standard STPs and packers.

Size Guide + How to Measure

Cake Bandit sits low, on your hips, not your waist, so sizes go by your hip measurement. Measure around the widest part of your hips and seat. Between sizes? Size down if you like a snug fit or pack heavy. Underwear is final sale, so measure before you order.

XS	24"–26"
S	27"–31"
M	32"–35"
L	36"–38"
XL	39"–42"

As a return customer, I have to say the new waistband is a game changer. So far, they don't nake my hands feel like velcro! The fit is great with minimal ride up. The struggle to find the perfect stp is real and I still don't utilize the pocket for it as the placement doesn't quite feel or look as natural. That being said I don't even worry cuz the fit of the boxers is perfect so I know my honey stick won't fall out! I gotta adjust occassionally, but hey, all guys adjust rt? At the time of my order the right size of harness wasn't available but I will order that as soon as it is. The instructional video makes it look well thought out and functionall! Thank you all for be here for us!

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.
