What's the difference between Cake Bandit packing underwear and STP underwear?
Packing underwear has a built-in front pouch that holds a packer or STP device — no separate harness needed. STP underwear is flat-front with no built-in pouch, designed to be worn with a harness or clip-on STP holder. If you want all-in-one convenience, go packing underwear. If you prefer to use your own underwear with a harness, STP underwear or a Cake Bandit harness is the move.
Do I have to use a packer with packing underwear?
No — you can wear Cake Bandit packing underwear without a packer. The pouch sits flat and comfortable on its own. Many people wear it daily just for the fit and gender-affirming cut, with or without a device inside.
How often should I replace my packing underwear?
Packing underwear works harder than regular pairs — the added weight and movement of a packer puts constant strain on waistbands and pouch seams. We recommend checking in at the 6-month mark for daily-wear packing pairs, rather than waiting the full 9–12 months. Watch for elastic that's lost its tension, a pouch that's shifting, or fabric thinning in the seat or gusset. Read the full guide →

What's the return policy on Cake Bandit underwear?
All underwear, harness, and anything that touches below the belt, sales are final for hygiene reasons. Please measure carefully before ordering — use the size guide above and reach out to hello@transguysupply.com if you're between sizes or have questions. We'd rather answer your question before the order than after.
I have a cycle — is there anything for me?
