Jump in blue. Come out red. Our Blue-to-Red color-changing swim trunks pull off one of the boldest color flips we sell. Dry, they read as a clean ocean blue — totally normal-looking until the moment they hit water. Cool water triggers the thermochromic dye and the fabric shifts into a deep, attention-grabbing red.

The science: thermochromic dye in the fabric reacts to temperature change. Cooler water = red. Warmer air = blue. Step out of the pool, dry off, and watch the transition happen in reverse. The effect is wash-safe and works as many times as you want.

5" inseam. Built for the guy who wants the loudest reaction at the pool deck.

Wasnt reall y expecting it to work this good but holy crap

Hubby loved his pair! Getting another in his Cowboys Blue!

Spilled some beer on them and people freaked out. Now everyone wants a pair.

Perfect for a day on the boat. When you're hot they're 1 color, then when you cool off, they're a totally different pair of shorts. Came in like 4 days too.
