What kind of underwear do astronauts wear?

Astronauts wear specially designed underwear called "Maximum Absorbency Garments" (MAGs), which are essentially adult diapers. These garments are designed to absorb waste and maintain hygiene in the microgravity environment of space, where traditional clothing and methods of waste disposal are not practical. MAGs are made of highly absorbent materials and feature multiple layers to prevent leakage and ensure maximum comfort for the astronauts during their missions.
