You won’t find flatter, more inconspicuous and lightweight wallets anywhere. These will carry all you need for any journey, whether it’s a quick errand to the store, or riding beside wildebeest in Africa. They’re better for your back, and help prevent wallet sciatica. Each style comes in both leather and ripstop nylon (which is flatter than flat!). Carry nice in front or back pocket. Patented too, believe it or not. The ‘Executive’ is most recommended.
Holds a passport, about 6-10 cards, plus bills.
