Taking the classic concept of a bifold wallet and turning it on its head, the Trayvax Axis is an impressively robust and minimalist cash and card carrier that fits as well in a back pocket as it does a front. It also has a capacity of up to 14 cards, 8 bills, and has a hideaway pocket for some coins or a key. Still, it weighs just 4 ounces and is only 0.5 inches thick thanks in part to its revolutionary stainless steel construction. Plus, it features a built-in money clip, easy-access identification window, and a mil-spec paracord attachment. And, of course, it was sourced from and handmade right here in the USA and comes with the brand's lifetime heirloom warranty.
