DEF CON Safe Mode T-Shirt & Gold Membership



In celebration of 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!

Sometimes you need to reboot the system to get things working again. We thought that was very fitting for the world during 2020. EFF created this t-shirt for DEF CON Safe Mode, and along with its glitchy design, this t-shirt incorporates our most challenging puzzle yet. 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!
