Meet Tender

We're setting
the standard

for activewear.
Clean fabrics.

Performance apparel has spent decades relying on petroleum derived synthetic fabrics. We believe there is a better way.

Tender creates beautifully performing activewear using thoughtfully sourced natural materials.

Microtencel

High Octane

THE CLEAN STANDARD

Better movement starts with better materials.

Most activewear puts performance first. We think it should come with peace of mind. So we chose certified clean fabrics that feel incredible and hold up through everything.

Certified organic

Grown without synthetic pesticides, certified at the fiber

Tested clean

Third-party tested for what you don't want on your skin

Never plastic

No standard spandex, no petrochemical shortcuts

Because what sits closest to your skin deserves the same care as everything else you do for your health.

We didn't set out to create another activewear brand.

We set out to create activewear we'd actually feel good wearing.

When we started looking into what most performance fabrics were made from, we realized there had to be a better way. One that didn't ask you to choose between performance and peace of mind.

Tender was built around a simple belief: the clothes you wear closest to your skin should be made with just as much care as the choices you make for your health. That's why every fabric, finish and manufacturing partner is chosen with intention.

It's activewear, rethought.

- with love, Lily
