C is for coffee. That’s energy.
Bert at the chalkboard. Wild white hair. Brown jacket. The equation that changed the world — rewritten. E = mC², where C is coffee. Below the board: “That’s Energy.” The pun writes itself. The hoodie wears even better. Back print on midweight fleece with a kangaroo pocket.
Sand — warm and neutral, lets the chalkboard green and Bert’s wild hair do the talking. Select your size above.
The Design Story
Bert has been a vampire, a mummy, a cubist portrait, and a moka-pot Mona Lisa. Now he’s a theoretical physicist. The wild white hair. The brown tweed jacket. The chalkboard. Everything about this design says “genius” — and then you read the equation and realize the genius is just really, really caffeinated. E = mC², where C stands for coffee. The math checks out.
This is the crossover piece for the person who has science puns on their coffee mug and coffee puns on their lab coat. The chalkboard green pops against the sand colorway, and the back-print format gives Al Bert-stein’s full lecture room to breathe. It sits in the Brew Good Vibes collection alongside the Art + Coffee series — different subject, same energy: take something iconic, add coffee, make it Bert. See all Clothing & Gear →
