Hydrochromic is a term used to describe a type of material that changes color when exposed to water. In the context of swim trunks, hydrochromic materials are used to create a unique and dynamic look. When the trunks come into contact with water, the material changes color, revealing a hidden design or pattern. The color change is temporary and returns to its original state once the fabric dries.

Absolutely mind-blowing swim trunks!
"These are hands-down my new favorite pair of shorts. The quality and fit are spot on, but the best part is the hidden graphics. They look like great solid trunks until you get in the water—then the designs appear out of nowhere! It’s such a cool effect, and I get compliments every time I’m at the pool. Highly recommend!"
