I have used the Bellroy Travel wallet for over 7 years and I still love it as much as I did from day 1.
It easily allows me to carry my passport with me everywhere and has some helpful features, like a pen for filling out custom form.
It is available on Amazon for $119 (link to product on the image below)
Here is a video review I did on the Sample the Culture site a while back. Is is still relevant and I highly recommend getting this if you are looking for a lifelong passport wallet.
