Elastic belts are free size and normally don’t tear at all. meaning they can last for life.
I am kind of surprised that they are not commonly recommended in the anti-consumption/ buy it for life communities. Despite the fact that replacing normal belts with them at scale would save the world shitload of resources that are spent on normal belts annually.
Side note: I don’t recommend wearing jeans or suit trousers on daily basis, as there is more durable options that can last for longer time.
Photo is for example, as this is a generic item.
Leather belts tend to wear out at the holes and you’re always playing with too tight too loose.
Work dress/work belt I went with a Ratcheting one for pretty cheap on Amazon. Its like new 3y later. Def fake/cheap leather though.
For everyday, I got a nylon (?) Belt with a plastic latch clasp. It’s been 6y, like new. And it doesn’t set off metal detectors.
