Because the Utility Belt was starting to sag.

Yes, your 'old-school' Utility Belt could no longer support every utterly ridiculous bat-themed concoction deemed "necessary" for every crime-fighting excursion.

I mean, the Bat-Thermos? The Bat-Beaver Trap?? The Bat-Selfie Stick?? Right, it was time to drop the unnecessary equipment and embrace simplicity. 

It was time to lose the old belt and embrace the weightless freedom of our Batman Classic Symbol Black Web Belt.

Made from resilient web belt material, this Batman web belt for men and women features a single, solitary Batman symbol adorning the buckle. And that's it.

And, being a web belt, it's an adjustable, pants-securing implement.

Solid metal buckle! Yes, it's a solid-metal buckle featuring an enamel insert layered with that singular Batman symbol.
