100% of net profits from this shirt go to the Bitcoin Red Team via OpenSats through December 31, 2026.

The Bitcoin Red Team, now for your head. This embroidered dad hat carries the same slashing, brushstroke logo that honors the volunteer researchers who rallied after the Coldcard firmware exploit — the whitehats who tore through hundreds of open-source projects to keep self-custody safe. Clean red-and-white stitching on a classic low-profile cap, worn by the people who understand that "open source" only means anything if someone's actually reading the code.

Net profits from this hat go to the Bitcoin Red Team via OpenSats. Buying it isn't just repping the mission — it's funding the auditors and maintainers defending the network. It's an everyday piece for the verify-everything crowd: throw it on for meetups, conferences, or a coffee run, and let it start the conversation. Don't trust. Verify. And back the people doing the verifying.

Here's the rundown: an unstructured, six-panel, low-profile cap in 100% chino cotton twill, with a 3⅛" (7.6 cm) crown and six embroidered eyelets. It finishes with an adjustable strap and an antique buckle for a comfortable, one-size fit. Blank product sourced from Vietnam or Bangladesh.
