Bitcoin Accessories

Bitcoin accessories from Bitcoin21 are the small things you reach for daily: socks, caps and swim shorts. Each one carries the Bitcoin21 mark, embroidered, in orange or tone-on-tone.

Bitcoin Socks — our best-selling piece

The Bitcoin Socks are made from 80% cotton, 17% polyester and 3% elastane. An extra-high ribbed cuff stops them slipping down, whether you wear trainers, boots or running shoes. They come in black and white — white for sport, black for everything else — with the orange Bitcoin21 logo on the shaft. From €15, they are an easy first piece, and they work well as a gift because sizing is less tricky than with a hoodie. Wash them inside out at 30 °C and keep them away from the dryer; heat wears out the elastane in the cuff.

Caps for sun and everyday

Two caps, €30 each, both organic cotton and both one size, and both shade your eyes in summer. The Bitcoin Cap uses Flexfit with a snapback press-stud strip that adjusts in fixed steps. The Washed Bitcoin Cap is a softer 6-panel cap at 280 g/m², freely adjustable with a hook-and-loop strap. The details of both, including the tone-on-tone versions, are in the Bitcoin caps collection.

Bitcoin Swim Shorts

The Bitcoin Swim Shorts with embroidered logo are made from recycled polyamide in a ripstop weave: light, tear-resistant and quick to dry, so you can walk from the water to a café without discomfort. Elastic waistband, organic cotton drawcord, mesh inner lining, two side pockets and a back pocket. Double stitching at the side seams and crotch adds strength where the load in the water is highest. The orange logo sits on the leg. Sizes XS to XXL, €37. The Bitcoin Swim Shorts Privacy carry the logo embroidered tone-on-tone low on the leg, also €37. In a suitcase they take up little space and do not crease.

How do the small pieces stay in shape?

Each accessory has its own care routine. Socks: 30 °C, inside out, no dryer. Caps: hand wash only, cold, then air-dry with the brim held in shape. Swim shorts: rinse in clear water after every swim, because chlorine and salt otherwise stay in the fabric and attack the fibres; machine wash at 40 °C, no tumble dryer. These few steps protect both the embroidery and the elastic parts.

Everything Bitcoin21 makes, from T-shirts to jackets, is in Bitcoin merchandise.
