What's the difference between packing underwear and a harness?
Packing underwear has the pouch built in — put it on and pack. A harness lets you pack while wearing your own underwear. Both hold securely all day. It comes down to whether you want an all-in-one pair or the flexibility to use underwear you already own.
Which style works with an STP device?
The Cake Bandit STP Boxer Briefs are built specifically for stand-to-pee use. The Packing Harness and O-Ring Harness also work with most STP devices when positioned correctly. See our STP Guide for full positioning tips.
How do I size Cake Bandit underwear?
Cake Bandit sizes by hip/waist measurement: XS 24–26", S 27–31", M 32–35", L 36–38", XL 39–42", 2XL 43–46", 3XL 47–52". If you pack heavy or want a firmer hold, size down. For all-day comfort, size up. When in doubt, size up.
Can I return or exchange packing underwear?
All underwear and harness sales are final for hygiene reasons. We strongly recommend measuring before ordering. If you have questions first, email hello@transguysupply.com — a real person will help you pick the right size and style.
Do you ship discreetly?
Always. Every order ships in a plain, unmarked mailer. The return address reads "Shipping Dept." only — no product names, no company name on the outside.
