This size is based on the layout of the Tyvek MICRO, but the best construction methods from fabric and leather are applied using the Soft Shell material. If you have 8-12 cards, you’ll enjoy a wallet that doesn’t weigh you down!
After an extensive search to find an ultra durable yet thin material, I tracked down a technical fabric mill capable of producing exactly what I was after. They create materials for such companies as The North Face®, Under Armour®, and even Gore®... the makers of Gore-Tex®.
In order to fund the huge minimum quantity required to produce it, the Kickstarter community helped raise over $150k and the Soft Shell was born.
