Open Source Must Win — Classic White Tee

The same flag, at a friendlier price. Our Open Source Must Win design, heat-pressed by hand in our Massachusetts shop on a classic white cotton tee.

Why it costs less: we press these ourselves instead of routing them through a print-on-demand factory — you save $12 versus the garment-dyed tee. The trade: each shirt is made to order, so allow a few extra days before it ships.

• Classic-fit white cotton tee
• 11" × 11" heat-pressed front print
• Pressed to order in-house — allow extra production time
• Care: machine wash cold, inside-out; hang dry or tumble low to keep the press crisp

Pair it with the book: wear the flag, read the field manual — Open Source AI: Month One ($19).
