Every system that lasts is built on something solid.
21 : Foundation takes its cues from Ethereum — the base layer where ideas become infrastructure and movements turn into code. It represents stability, consensus, and long-term execution rather than noise. This is the layer others build on.
Constructed on a Gildan Softstyle tee, 21 : Foundation delivers lightweight comfort with reliable structure for daily wear. Soft ring-spun cotton creates a smooth, broken-in feel, while reinforced stitching ensures durability through constant use. Clean lines and a regular fit make it easy to layer or wear on its own — understated by design.
This isn’t about being early.
It’s about being permanent.
