Bitcoin Caps
Bitcoin Caps from Bitcoin21 come in two shapes. Both are mostly organic cotton, have the embroidered Bitcoin21 logo on the front and are unisex in one size. They're €30 each.
Bitcoin Cap with Flexfit
The Bitcoin Cap combines Flexfit with a snapback strap at the back, which lets you set the width in fixed steps. It's made from 98% organic cotton and 2% elastane and comes in Dark Grey and Navy.
Washed Bitcoin Cap
The Washed Bitcoin Cap is a 6-panel cap in 100% organic cotton at 280 g/m². It's been washed, which gives it a slightly faded look, and the colour varies a little from cap to cap. At the back there's a hook-and-loop strap, so you can adjust it to exactly the fit you want. It comes in Navy Blue, Black, Brown and Pale Green.
Bitcoin Caps with a tone-on-tone logo
If you'd rather wear the logo subtly, the Bitcoin Cap Privacy in Dark Grey, Black and Navy and the Washed Bitcoin Cap Privacy in Navy Blue, Black, Almond Green and Dark Camel have the same cut, with the logo embroidered tone on tone. The price is the same too.
Common questions about Bitcoin Caps
What size are the Bitcoin Caps?
All our caps are unisex and one size. You adjust the Bitcoin Cap with the snapback strap and the Washed Cap with the hook-and-loop strap.
Which cap is right for me?
The Bitcoin Cap has Flexfit and adjusts at the back with press studs in fixed steps. The Washed Cap has a slightly faded look and adjusts freely with the hook-and-loop strap. So it mostly comes down to which closure and which look you like better.
How do I wash a cap?
By hand in cold water with a mild detergent. No tumble dryer and no iron. Let it dry in the air and keep the brim in shape while it does.
Is the logo embroidered?
Yes, on all four caps. On the Privacy caps it's embroidered tone on tone, in the same colour as the fabric.
How much is shipping?
Shipping is €4.99, and orders from €75 ship for free. That applies to Germany, Switzerland and every EU country we deliver to.
