Swim 4.5" Shorts - Jelly Magic
Wear it with
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.

All product life span is improved with hand wash and lay flat drying, but if you don’t have the ability or time, delicate wash in your washing machine is fine and low tumble in the dryer. This also extends the life of your prints.
High heat can damage the spandex and break it down or lose the retention quality.
For any technical fabrics, fabric softeners break down the performance properties. Stay away from added fabric softeners, in general.
