Congratulations. 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-resistnat 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 had been using a Soft Shell for the last 6 months or so to test longevity, but after no signs of wear and a new Cubic sitting on the table from a photo shoot, I couldn’t resist switching over to it. 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...

Congrats to Pebble Time!

I first met Eric a little over a year ago shortly after my Kickstarter campaign for the Tyvek SlimFold MICRO. It turned out he was a user of the Tyvek SlimFold Original and had been following the Kickstarter as well. We had a great brunch and he gave me some advice for running the Kickstarter and other general business stuff. I met with Eric again a few weeks ago and based on how relaxed he was, I would have never guessed he was right on the verge of launching a record-breaking project. (In case you haven't heard, they raised $5m in about 5 hours and are now over $11m.) We walked through their sprawling Palo Alto office which now houses about 130 folks passionate...
