Short of holding your cards & bills together with an elastic band, the HuMn wallet is tough to beat in terms of minimalism. Two plates of aluminium and an elastic shock strap make up the HuMn, which then adapts to your liking, becoming only marginally thicker than whatever is put into it. You can also sleep easy knowing that RFID thieves won’t be able to steal your credit card and bank information straight off of your cards.
