Pi Day Tee | Short Sleeve
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 back—bold, balanced, and unmistakably TBP. Crisp white ink contrasts against deep navy for a look that’s 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 you’re quietly solving next.
