Capitalizing on their legendarily impressive 10XD fabric - a proprietary textile that's 10 times stronger than steel, as well as waterproof, sweat-proof, and machine washable - the folks at Pioneer Carry have reinvented the classic bifold wallet with their 10-card capacity, RFID-blocking Flyfold. The indestructible fabric is bolstered by reinforcement bar tacks, which make this perhaps the toughest bifold ever made. On top of that, it also boasts a spacious main compartment, perfect for a wad of cash or some loose papers and/or receipts. But the cherry on top of the cake is the FutureForm technology built right in - which will allow the wallet to break in beautifully over time without ever breaking down. This could very well be the last wallet you ever need.
