What brand of adult diapers do astronauts and fighter pilots use?

Military, store bought, mail order. . .doesn’t matter. They’re universal.

I would imagine they’re custom made, heavy duty.

Weightless Waste Matter diapers are very popular with asstronauts! ;)

Navy fighters wear a product called “Top Buns”

Reminds me of that female astronaut (or was it a wannabe-, or trainee astronaut), that went on a road trip to confront another female that supposedly was a competition to her for her love interest.
To not lose valuable time she wore an astronaut’s diaper.
Don’t know the brand though.
