We have a short list of travel essentials, and a passport wallet is right next to the top (the top is a luggage scale, just FYI). This leather passport wallet ($86) pretty much fits the bill. Aside from a place for your passport, it has room for your plastic and cash. It’s made of vegetable-tanned leather and brass, nickel-plated rivets, no dyes. All you need are some plane tickets and you’re set.
