21M Cap

Overview

The 21M Cap is a Nuri own-brand cap embroidered with "21M" — a nod to Bitcoin's fixed supply of 21 million coins, the property that underpins its scarcity. It's a subtle insider reference rather than a logo-heavy hat: most people will just see a clean embroidered cap, while Bitcoiners will get it immediately. Made from cotton twill with an adjustable back, it's built as an everyday cap that fits a range of head sizes.

The strengths are simplicity and wearability. Cotton twill is durable and breathable, embroidery lasts longer and looks better than a printed graphic, and the adjustable strap means one size genuinely fits most. The "21M" motif is a quiet, meaningful reference for people who care about fixed-supply money. You can buy it with Bitcoin like everything else. The honest caveats are minor: it's a single design, the reference is deliberately obscure to non-Bitcoiners, and as with any cap, fit comes down to the adjustable strap's range. From around $30.

Buy it if you want a clean, everyday cap with a subtle fixed-supply reference and appreciate embroidery over loud prints. If you want a bold, obvious Bitcoin statement piece, this understated design intentionally isn't that.
