All-ett is a registered trademark for the All-ett billfold, a patented wallet (U.S. patent 6,050,311) that reduces the thickness of a full wallet by more than half, while remaining about the same size otherwise. This is accomplished by a side by side card pocket design that reduces the thickness of the contents 50% and the use of thin modern water repellant material called ripstop nylon also known as spinnaker cloth that is about one fifth as thick as leather.
