Shhhh... I'm Doing Math Shirt Unisex

You're hitting PRs today. You're even setting new ones. The blood is rushing to your head and it's hard to do math that way - we understand. That's why we made this comfy, funny, loose-fitting shirt.

Available as either a t-shirt or a tank top, both are great for working out in. Choose your style from 4 different colors!
