Our take on the Math Pi Hoodie 3,14 Pi Number Hoodie

A pullover hoodie printed with a 3.14 pi design, aimed at math fans, students and teachers. It is a classic-fit unisex style in a cotton-polyester blend, with a twill-taped neck and mid-weight 8.5 oz fabric. Print-on-demand apparel like this competes on design and fabric rather than construction, so expect a standard blank hoodie with a novelty graphic. It suits gift buyers and Pi Day wear more than anyone wanting a heavyweight everyday hoodie.

Questions and answers

What is the fabric and how does it wash?
Solid colors are 80% cotton and 20% polyester; heather grey is 78/22 and dark heather is an even 50/50 blend. Machine wash cold with like colors and tumble dry low.
Is this hoodie warm enough for winter?
It is an 8.5 oz mid-weight pullover, fine for fall and mild winter layering. It is not a heavyweight fleece for deep cold.
How does the unisex sizing fit?
It is a classic unisex fit, so women often size down for a closer fit. Check the size chart rather than assuming your usual men's or women's size.
Is it a good gift for a math teacher?
Yes, the pi design fits Pi Day, birthdays and end-of-year gifts for teachers, students and engineers. It is a novelty piece, so pick a size they would wear casually.
Does the print hold up in the wash?
Washing cold and drying low, as the care label says, is the best way to protect the graphic. Hot water and high heat are the usual causes of print cracking.
