I recently got a Deuter travel wallet (Deuter is a German Backpack/Hiking equipment manufacturer, and their stuff is usually very well made. I’ve had the same trekking backpack for 10 years now, and the way it’s looking, I’ll have it for another 30 at least).

Tbh the wallet is not very stylish… But it’s very well made, lots of slots for card, cash, and even passport, and if it does get grungy, you can throw it in the washing machine.

There’s also a smaller option if this one is too big.
