Performance meets conviction. The men's Bitcoin ‘B’: Quarter Zip Pullover is built on an Adidas blank — 100% recycled polyester with sweat-wicking technology, UPF 50+ sun protection, and a hydrophilic finish that keeps you cool, dry, and moving. The Bitcoin ‘B’ graphic does the talking.
A clean quarter-zip silhouette with a self-mock collar, contrast Adidas logo on the left sleeve, and a block height embroidered on the right sleeve — marking the exact block when this design went live on-chain. A timestamp you can wear. Regular fit that works from the trail to the street. Available in Black, Collegiate Navy, and White. Sizes S–3XL.
