About
SumRace Shop is apparel for people who solve — minimal designs in JetBrains Mono (yes, the actual font), printed on blanks worth wearing daily.
No logo slaps, no gift-shop energy. A 2^n − 1 on the left chest, a magic square front and centre. The kind of thing other puzzle people notice and everyone else just sees as a clean shirt.
Every item is printed on demand — no inventory, no warehouse, no waste. Your order goes straight to production when you check out.
