Soft Shell


The new SlimFold™ Soft Shell line is made from a material which feels similar to a ski jacket, yet is so abrasion resistant, it’s rated for use in motorcycle wear. It was even subjected to 70mph crash-testing on real pavement during development.

  • Stronger than leather
  • Bluesign® certified environmentally friendly material
  • Waterproof and machine washable



Made from the ultra rip-resistant FedEx mailing envelope material, the resulting SlimFold™ Tyvek line is the world’s thinnest wallet. Technically a sheet plastic, Tyvek is most commonly known for its use as FedEx packaging that’s almost impossible to open without getting scissors.

  • Thinnest possible option
  • Ultra rip-resistant
  • 25% post-consumer recycled content and recyclable (HDPE)
  • Waterproof
