A classic, done properly.

This short sleeve Pi Day tee features the official Tau Beta Pi Bent on the front left chest and the full Pi Day design on the backbold, balanced, and unmistakably TBP. Crisp white ink contrasts against deep navy for a look thats sharp without trying too hard. It reads engineer, not gift shop.

Soft, breathable, and cut for everyday wear, this shirt moves easily between campus, office, and whatever problem youre quietly solving next.
