Do-mug - DrT - Tee

Our Dou-Mug t-shirt is perfect for those who admire Dr. Trefor's graphic math tees. Crafted of 100% cotton, it features a relaxed fit and a fun front print with a classic example of topology illustrating objects that maintain their essence when deformed. It's a hit for topologists, who love the joke that a mug and a donut, both with just one hole, are topologically equivalent!
