Hippotenuse — The Cute Maths Geek T-Shirt

Show off your inner geometry geek (and your excellent taste in puns) with our Hippotenuse tee. A cheerful hippo in full professor regalia struts confidently across the chest, declaring that being “sqrt(hippo² + tenuse²) = awesome” is the only theorem that matters. It’s the perfect conversation-starter for study group, maths club, or laid-back weekends when you want your humour as crisp as your angles.

Why you’ll love it

• Maths-class meets streetwear – playful graphic that only the initiated will fully get.

• Soft, breathable cotton knit – comfy enough for marathon revision sessions or all-night coding sprints.

• Unisex regular cut – neither boxy nor clingy; sits just right on every body type.

• Colour-fast print – bright pigments that stay sharp wash after wash.

Find your fit (read this part!)

Our shirts follow ASIA sizing, which runs about one to two sizes smaller than standard US/EU cuts. Use the quick guide below—if you’re between sizes, go up rather than down:

*Measured flat. Please allow a 1–3 cm variation due to manual measuring.

Pro tip: If you usually wear a unisex US-L, order ASIA XL. When in doubt, lay your favourite tee flat, measure bust width and length, and compare.

Care instructions

1. Machine wash cold, inside-out.

2. No bleach or harsh detergents—keep that hippo happy.

3. Tumble dry low or hang dry for longest life.

4. If ironing is a must, press inside-out, avoiding the print.
