SlimFold MICRO Tyvek Wallet

The SlimFold MICRO uses DuPont Tyvek — a tear-resistant, waterproof non-woven material — to create a wallet that's under 5mm thick and under 1 oz. Holds up to 10 cards with an RFID-blocking bonded aluminum layer that adds no thickness. Made in the USA with a 5-year warranty. If you're transitioning from a bulky bifold to minimalist carry, this is the lowest-risk entry point — affordable, waterproof, and genuinely pocket-disappearing thin.
