Kestos in crystal water
Beyond Swim, Beyond Sweat

One set. Every terrain.
Zero compromise.

Your swim set can't survive a beach run. Your activewear dissolves in chlorine. Until now, moving between elements meant packing two outfits.

Kestos was built to end that trade-off. One set that holds up from sand to surf to studio — comfortable enough to wear from sunrise to sunset.

The Signature Set

Effortless Flow. Intuitive Movement.

A minimal silhouette designed for light, fluid movement. The crossed-front follows your body's natural lines — inspired by the original 1925 Kestos geometry. Less structure, more freedom.

Born in 1925.
Reengineered for
Every Element.

In 1925 London, Rosamond Llewellyn-Jones crossed two silk handkerchiefs and created the first modern bra — support through tension, not compression. No wires. No boning. Pure geometry, working with the body.


A century later, we've taken that same crossover geometry and reengineered it into sportswear that moves between land and water. Same principle. Built for a new century.

How It Feels

Worn. Tested. Loved.

"Took this on a family beach holiday. I needed something I could actually swim in, then walk to lunch without changing. The Sculpt Set does exactly that. The white didn't go see-through, the UPF50+ meant I wasn't layering sunscreen every 30 minutes. It just works."

"The double-strap X-back is the most stable swim top I've tested — diving, jumping, overhead serves, zero shifting. I've worn it hard for six weeks. No pilling, no stretch-out, chlorine hasn't touched it. My other swim sets at $200 didn't last half as long."

"I have extremely sensitive skin and most bras leave red marks within an hour. The elastic straps are genuinely different — soft contact means soft contact. I wore it for a full beach day and forgot I was wearing it, which is the highest compliment I can give."
