I was watching a video on YouTube recently, and it was a talk by Mr. Rory Alsop (a moderator on Stack Exchange site Information Security). The guy was wearing a Information Security T-shirt. Does Stack Overflow have such T-shirts and if yes where can we buy them?
From the link in the comment:
We'll continue to make swag, and continue to gift it to people in special circumstances, but you won't be able to purchase it anymore.
