Description The PROOF Operator is a slim RFID-blocking wallet built on an aerospace-grade aluminum frame in satin gunmetal, wrapped in olive drab ballistic nylon and black full-grain leather. It holds up to 25 cards inside the frame and 20 folded bills under the rear strap, at 1.75 oz. How It Carries Cards sit inside the aluminum frame rather than in pockets, so the plate takes the pressure instead of the card edges and protects them from bending. RFID-blocking material is built into the interior. A pull tab on the front fans the stack out in one motion. An elastic strap across the back holds folded bills flat against the plate. Ballistic Nylon And Full-Grain Ballistic nylon is a dense, tightly woven synthetic with a flat matte surface. Here it runs in olive drab alongside black full-grain leather, over a brushed satin gunmetal plate. The metal is cut, sanded and finished with rounded corners, so the wallet moves in and out of a front pocket without catching. Designed by a team of U.S. military veterans and engineers. Protected by US Patent No. 12,604,959. Covered by a lifetime warranty against damage and loss.
