Our classic 6” Fly with a little something extra – these high quality boxer briefs come with a deep pocket to securely accommodate a soft FTM packer. Our packing underwear keeps your packer in place for all-day comfort.

For best fit, the packer should sit at the bottom of the inside pocket. The top of the pocket has a soft elastic strip to hold the packer securely in place against the body once positioned.

While you can open the fly to access what you are packing, because the packer sits inside a pouch, STP use is not recommended. This is a great choice for folks who want some fabric between their skin and their packer.

With our line of trans underwear, you can comfortably wear your packer on a daily basis. Each pair of our packing underwear has been made with reinforced seams and breathable fabric, keeping you fresh and supported from morning to night.
