DEF CON 26 T-Shirt & Gold Membership Certificate
To celebrate EFF's 30th anniversary, we're offering vintage DEF CON T-Shirts with a certificate that you can redeem for a year-long EFF Gold Level membership!
EFF created this neon shirt design to pay homage to Keith Haring and his playful, yet sometimes sinister, view of human nature. You can read more about the design and the puzzle solution here! You can also get our newest member t-shirt by going to our donate page!
This t-shirt comes in sturdy Classic Fit, or a super-soft Slim Fit for all bodies. Be sure to check out our size chart. Size options are limited, so act fast!
