Train clean isn’t a trend — it’s a standard.

Activewear sits on your skin for hours, through sweat, friction, and repeat wear. We believe performance should come with peace of mind. That’s why we prioritise third-party testing and certified fabrics in the ranges where you train hardest.

What OEKO-TEX® Standard 100 means

OEKO-TEX® Standard 100 is a globally recognised textile certification. It means the fabric has been tested for harmful substances against strict criteria.

In practical terms: it’s an independent check designed to support safer choices for textiles worn close to the skin.

  • What OEKO-TEX® Standard 100 means

    OEKO-TEX® Standard 100 is a globally recognised textile certification. It means the fabric has been tested for harmful substances against strict criteria.

    In practical terms: it’s an independent check designed to support safer choices for textiles worn close to the skin.

  • Why it matters for activewear

    When you train, your skin is warm, you sweat, and fabric sits close for long periods. For us, “train clean” is about reducing unnecessary exposure while still delivering high performance.

    We look for:

    • Independent, third-party testing
    • Certified fabrics where it matters most
    • Performance construction that holds up to training and repeat wear

  • Certified ranges

    The following Viren ranges feature OEKO-TEX® Standard 100 certified fabrics:

    • Prowess
    • Higher Power


    (We’ll always be transparent about which ranges are certified and will update this page as testing expands.)

Our promise

We’re building Viren for women who train — strength days, studio sessions, and everything in between. “Train clean” is part of how we design: tested fabrics, thoughtful construction, and performance that lasts.

Built for resilience. Powered by you.
