It's a slim-profile belt designed to hold your shirt in place, the way a regular belt holds your trousers.
When slipped on, the belt will secure your shirt in place and always keep it tucked in, ensuring it stays in place no matter how much you move throughout the day.
Heck you can remove your pants for any reason and the shirt will remain in perfect condition.
