Let Me Guess.

We Didn't Fool You?

We were messing around - but honestly, polyester activewear ISN'T a joke. It sheds microplastics against your skin. It often contains toxic chemicals. And it's in 99% of the brands you probably wear.

The Problem With Traditional Activewear

99% of activewear is made with cheap, plastic-based fabrics like polyester, nylon & spandex.

Here’s why that’s a problem:

Polyester is plastic. Which means...

  • It sheds microplastics onto your skin

  • It often contains toxic plastic chemicals

  • It traps heat, sweat & bacteria against your skin

Collage of news headlines discussing BPA in athletic clothing.

Plastic based fabrics have been shown to contain:

  • Microplastics

  • BPA and Phthalates

  • PFAS ("Forever Chemicals")

  • Formaldehyde

And these chemicals in polyester have been linked to issues like...

  • Fertility impacts

  • Hormonal disruption

  • Decreased sex drive

Shop Natural Activewear

Your body can absorb these chemicals through your skin - especially when sweating.

Hot & sweaty while exercising. Pores open. Research shows these chemicals absorb right in. And it's even worse if you sauna...

You optimize everything. Except what's against your skin.

You spend hundreds a month on supplements. Track you WHOOP data. Eat clean & avoid processed foods.


Then you put on shorts made from the same material as a plastic water bottle. It doesn't make sense.
