Situated firmly in the space between style and substance, the Ion wallet is a reimagining of the classic bifold - but this minimalist offering is so much more than just that. For starters, it offers two easy access slots for a total capacity of 8 cards plus some folded cash. And those are secured by 4 close-stitched reinforcement bar tacks. But the star of the show is this wallet's construction of FutureForm heat-molded 10XD ripstop fabric - rated at 10 times tougher than steel per weight and holding the crown of strongest fiber on earth.
