Why Ondine?

Ondine is more than a name — it’s a story. Inspired by the myth of the water spirit, Ondine flows effortlessly between light, skin, and movement. She protects gently, moves freely, and lives in the warm glow of everyday sun.

At Ondine, we believe in sun protection clothing that feels like nothing — yet shields you completely. Designed for softness, breathability, and freedom of movement, our pieces let you live beautifully in the light.

Our name is a tribute to fluidity, protection, and effortless care — a reminder that true comfort moves with you, wherever the sun leads.

Your clothes should protect your skin

UPF stands for Ultraviolet Protection Factor — a built-in shield against harmful sun rays. Unlike SPF creams, UPF fabrics never wear off. They’re soft, breathable, and designed to protect your skin every day.
