Bitcoin Sportswear
Bitcoin Sportswear from Bitcoin21 isn't a cotton shirt with a new label. Technical polyester that wicks moisture away, in the same plain designs as the rest of the range.
Bitcoin Sports Shirt “Proof of Work” – for training
The Bitcoin Sports Shirt in technical polyester fits close enough to stay out of your way during training, and dries faster than cotton ever could. €30.
Bitcoin Running Shirt “Running Bitcoin” – 135 g/m² for the distance
The Bitcoin Running Shirt weighs 135 g/m², noticeably lighter than the sports shirt — built for longer distances. The name is a nod to Hal Finney's tweet from January 11, 2009. €30.
What comes along
The Bitcoin Socks from €15 and the Bitcoin Cap belong in this category too — both pieces that work as well during training as after.
Keep stacking sats.
