Swim 4.5" Shorts - Jelly Magic

Reveal an aquatic surprise with our water-activated fabric. When dry, black keeps its secrets hidden. But splash some water on it, and watch as gray jellies emerge.

How It Works

Our innovative color-changing technology responds to water contact. The moment moisture hits the fabric, the previously invisible jellyfish print transforms from black to gray. Once dry, the fabric returns to its sleek, all-black appearance—ready to surprise again and again.

Not to brag, but this is the perfect length swim bottom. Coverage? Great fit? Something that won't ride up or slip down while wet? Welcome to swim bottom nirvana.
