Bitcoin Polo Shirts

A Bitcoin polo shirt is the piece for when a T-shirt feels too casual and a buttoned shirt too formal. Bitcoin21 makes it in 100% organic cotton at 220 g/m², with a traditional polo collar, a button placket and the Bitcoin21 mark embroidered on the chest. All four versions cost €40.

Bitcoin Polo Shirt with orange logo

The Bitcoin Polo Shirt carries the small Bitcoin21 mark in orange. The straight fit looks tidy with the collar closed and relaxed with it open, and because the fabric is not too thick, it sits flat under a blazer. Finely finished cuffs complete it, and since the logo is embroidered, you can feel the stitching under your fingertip. If you want to show where you stand without making a statement of it, this is the one.

Bitcoin Polo Shirt Privacy in black, navy and grey

The Privacy polo is the same shirt with the mark embroidered in the colour of the fabric. Choose from black, navy and grey. From across the room it reads as a plain polo; at handshake distance the mark becomes visible. That makes it a natural pick for client meetings, conferences or dinners where you would rather not open with Bitcoin.

Where a polo fits in

Think of a client meeting without a tie, a conference day, a summer evening at a restaurant or a round of golf. What the polo is not made for is sport and heavy sweating: cotton soaks up moisture and stays wet. For training, the technical shirts in Bitcoin sportswear are the better choice. If you prefer an open neckline, the Bitcoin T-shirts follow the same principle.

What size, and how do I keep the collar straight?

The polo has a normal fit; our model is 1.90 m tall and wears XL. The size chart on each product page lists neck, chest and waist measurements, and if you fall between two sizes, the larger one is usually the better choice. Wash at 30 °C, since hot water makes organic cotton shrink. After washing, put the polo on a hanger and smooth the collar while it is still damp — it will dry straight instead of wavy. Turning the Privacy version inside out protects the tone-on-tone embroidery. A first wash before you wear it settles the cotton, and the measurements stay put after that.

The Privacy polos in black, navy and grey also belong to the Privacy Collection, alongside T-shirts, a hoodie, a sweatshirt, jackets and caps with the same quiet mark.
