Cake Bandit - STP Long Johns

by TG Supply


Long Johns Made for Use with an STP

Keep warm this winter with Cake Bandit's first-of-its-kind, stand-to-pee device, soft packer, and play prosthetic compatible long underwear. These soft long johns come with a shorter inseam, so they're perfect for those of us with a smaller stature as well as for taller folks. These are great for folks who work or play in the great outdoors or for cozying up inside (preferably lounging by a fire). You can also wear these as an athletic under layer when working out on colder days.

May you finally feel the childhood wonder of being able to write your name in the snow.

Smaller than the boxers

I found that the long johns, while comfortable, are slightly smaller than the same size of the boxers. I felt that they slipped down very easily and I don’t feel comfy wearing them outside my house.
