Love these wallets! Very cool. Super light and thin.

Flowfold wallets are built with the same high tech racing sailcloths used by the world's sailing elite. These cloths are composed of Carbon Fiber, Kevlar, Pentex or Polyester matrixes sandwiched between Mylar films. They are the toughest, lightest and most resilient cloths in the world due to their high tensile strength to weight ratios and ideal modulus of elasticities.
