About ONYX

Designed for women
who move with purpose.

ONYX was born out of a simple frustration. Every week on the court, the choice was the same: look good or feel comfortable. We knew there had to be a better way.

We set out to create timeless tennis and padel pieces that combine performance, comfort and understated elegance – both on and off the court.

2026

ONYX began
with one question.

Why is technical sportswear either beautiful or functional —
but rarely both?

We combined premium fabrics, thoughtful design and a feminine silhouette to create activewear that moves with you, supports you and makes you feel confident.

This is more than sportswear.
This is ONYX.

Made to move.
Made to be noticed.
