Swim Sport Compression Top

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.

Get sporty, sea style. Based on our best selling Compression Top, this swim top features 3 layers of Bahia fabric, which holds its shape and lasts longer for all-day water support.

Timothy ★★★★★ Sep 6, 2026

The water-activated design is such a fun touch — first time I wore it in the pool, the gray jellies slowly appeared and genuinely surprised me. The fabric dries black again pretty quickly, so it works as a normal top after the swim.

Ella ★★★★★ Sep 2, 2026

Diving in feels like a magic trick — the dry black top is sleek and plain, but the moment water hits it, those gray jellies pop up across the fabric. It's gotten a few stares at the pool, and the fit stays snug without riding up.

The water-activated fabric is such a cool trick—I drenched mine in the pool and the gray jellies appeared instantly, which made my kids laugh out loud. It dries back to plain black fast, too, so I can wear it to brunch after a morning swim without looking like a science experiment.
