Details

Same colours. Bigger adventures. Matching father and son swim shorts: one pair for dad, one for the mini, both printed with the same thermochromic (heat-reactive) pigment. A splash of water or the sun changes the colour, so you can watch them change together.

What's in the set

  • 1 x men's colour-changing swim shorts (S to 3XL)
  • 1 x kids' colour-changing swim shorts (sizes for ages 3 to 12)
  • Both in your choice of Purple to Blue, Orange to Yellow or Blue to Green

Why you'll love it

  • Changes colour instantly: a splash of water or the sun shifts the colour, cool water switches it back
  • Quick-dry fabric with a full elastic waist and drawcord on both pairs
  • Better value: save compared with buying the two pairs separately
  • Made for gifting: Christmas, birthdays and Father's Day

Fit & sizing

Choose dad's size (men's S to 3XL) and the mini's size (kids' S to 2XL, by age) separately. Between sizes? Size up, and check our size guide. Not quite right? Our 30-Day Happiness Guarantee has you covered.

Care

Rinse in cool fresh water after a swim and dry in the shade. Skip hot washes, tumble dryers and the iron, as heat can wear out the colour change over time.

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 switches 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. Not quite right? Our 30-Day Happiness Guarantee has you covered.

Can dad and the kids match?

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

Do you offer free shipping?

Free shipping Australia-wide on orders over $100. We'll email tracking as soon as your order ships.

What if they don't fit?

Please check the size guide before you order, as we don't swap sizes. If the fit isn't right, tell us within 30 days of delivery and we'll send you a one-time code for 25% off your next order. It's part of our 30-Day Happiness Guarantee.
