C = Coffee × Community. That’s Energy.
Bert as Einstein. Wild white hair. Lab coat. Glasses over the sunglasses. Standing at a chalkboard rewriting the most famous equation in physics: E = mC², where C = Coffee × Community. “That’s Energy.” Front print on gold ring-spun cotton. The summer companion to the sand hoodie.
Gold — warm mustard, the chalkboard green pops against it like a lecture hall in the afternoon sun. Select your size above.
The Design Story
The hoodie put Einstein Bert on sand fleece — cozy, professorial, the kind of piece you wear grading papers or pretending to. The tee brings the same genius to gold cotton and moves it to the front. The chalkboard, the equation, the wild hair — all chest-level now, readable before anyone gets close enough to check the math.
The equation is the real hook. E = mC² looks like physics until someone reads the subscript: C = Coffee × Community. That’s the SBOF philosophy hidden in a formula. Energy comes from coffee multiplied by the people you share it with. The pun name — Al Bert-stein — is the gateway. The equation is the philosophy. See all Clothing & Gear →
