Got questions?

Ask us anything
How do they change colour?

They're printed with a thermochromic (heat-reactive) pigment. Cool, they show their first colour. Warm them up in the sun or in warm water and they shift to the second, then cool water brings them back. Here's how it works.

Will the colour change wear out?

Look after them and they'll keep changing. Rinse in cool water, dry in the shade and skip hot washes, dryers and the iron.

How do sizes work in the set?

Pick dad's size (men's S to 3XL) and the mini's size (kids' S to 2XL, ages 3 to 12) separately. Between sizes? Size up. Backed by our 30-Day Happiness Guarantee.

Can dad and the kids match?

Yes. The Kids' Original comes in Purple to Blue, Orange to Yellow and Blue to Green, the same as dad's Original, or grab both in one go with a Dad & Mini set.
