The Stratos

Cool, composed and built for altitude, the PROOF Stratos minimalist wallet pairs stone gray full grain leather with a Brushed Navy Gunmetal plate and nickel bolts. Fine vertical brushing gives the deep navy metal a subtle sheen that shifts with the light.

Tonal gray stitching and an embossed PROOF logo keep the look clean and understated, so it works as well with a suit as it does with a flight jacket.

We've redefined minimalist wallets as you once knew them. Bland, cheap sheet metal sandwiching your cards is a thing of the past.

The PROOF Wallet incorporates fine full grain leather and aerospace metals into a sleek, ultra functional minimalist design. It allows carrying up to 25 cards safely and securely with built in RFID Blocking internal materials. We've topped it off with a snug cash strap on the back and an intuitive pull strap on the front for easy card access.

The PROOF UNRIVALED Guarantee: If you damage, or even lose your wallet, we replace it for free.

Risk Free Trial: We are so confident in our wallets' quality that we back it with our no questions asked FULL refund and return policy.

With PROOF, minimalist wallets are no longer just for high school kids. Upgrade your wallet with a professional, durable, and ultra functional Proof Wallet.

WALLET IN USE

A Navy and Gray Wallet Built for Clear Skies

When we set out to build not just a great wallet but the best minimalist wallet possible, our team prioritized protection, comfort, and intuitive performance. The Stratos takes that no-compromise design and gives it a cool, high-altitude finish. Its aerospace-grade aluminum plate protects your cards from bending or chipping, while built-in RFID protection ensures digital defense.

Navy and gray is one of the most versatile color pairings in menswear, and the Stratos puts it in your pocket. It’s a natural pick for pilots, aviation enthusiasts and frequent flyers, and an easy gift for anyone who prefers quiet confidence over flash.

Where Form Meets Function

We don’t believe that a minimalist RFID protection wallet should leave you stuck with a wedge of metal or leather. By consistently pushing the envelope on performance, we were able to create a wallet with a sleek aesthetic and rugged durability.

To ensure your comfort, we cut, sand, and finish the metal parts for a smooth wallet with rounded corners. Our team has also explored the limits of card storage to ensure maximum carrying capacity. Enjoy a wallet that can carry up to 25 cards on the interior and 20 bills in the exterior elastic strap. With its vertical wrap-around design, this wallet elegantly transitions from pliable accessibility to metal protection.

A Team That’s Always Seeking Perfection

Designed by a team of U.S. military Veterans and engineers, this wallet is the product of dedication to crafting the perfect minimalist wallet with RFID protection. While perfection may be impossible, we’ve come as close as we can. Our wallets will stand the test of time with unparalleled integrity. However, if they don’t meet your expectations, you can always reach out to our customer service to discuss your concerns. With our UNRIVALED Guarantee, you can return your wallet for any reason at any time.

Carry comfort and confidence with PROOF.
