Do-mug - DrT - Tee

If you share Dr. Trefor’s penchant for graphic math tees, you’ll love our Dou-Mug t-shirt! This relaxed fit, super-soft 100% cotton t-shirt features as its fun front print the classic example of topology, how something can be deformed without losing its essence; giving rise to every topologist’s favorite joke that a mug and a donut, each only having a single hole, are topologically equivalent!
