Reveal a prehistoric surprise with our water-activated Dinosaur Magic fabric. This isn't just any black board short—it's a wearable transformation waiting to happen. When dry, these swim shorts keep their secrets hidden. But splash some water on it, and watch as gray dinosaurs emerge! As the fabric dries, the dinosaurs gradually disappear back into the darkness, ready for their next appearance. How It Works Our innovative color-changing technology responds to water contact. The moment moisture hits the fabric, the previously invisible dinosaur print transforms from black to vibrant color. Once dry, the fabric returns to its sleek, all-black appearance—ready to surprise again and again. Hang loose with no worries. Our new 7” Board Shorts have a relaxed fit and longer inseam to go from the trail to the beach to the yard to pick up the mail that just got dropped off. Made from OEKO-Tex certified fabric and fit tested for all body types, we think our board shorts are in for the long game. So if you want a relaxed fit that’s up for anything, they’re for you.
