Your thin wallet search may be over. SlimFold™ makes the world’s thinnest, lightest, and strongest minimal wallets right here in San Francisco. Now with RFID blocking as an option. Let me help you pick the model that’s best for you...

Tyvek® and Soft Shell are the two materials available and they come in Original and MICRO size. Each model has several color/stitching combinations and an RFID blocking option.

  • Thinnest, lightest, and strongest wallets available
  • Innovative environmental materials with no animal products
  • Made in San Francisco

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. Despite having a fully functional money pocket, ID window, and individual card slots, it’s still the thinnest wallet made, both empty and full.

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

I’ve obviously used each of my wallets for extended periods during development and testing... and while I don’t have kids, I can imagine that picking between my models would be like asking someone to say which child they love the most. Each time I start using one, I find that I love it even more. And the Cubic is no...
