Gym Clothes, Without the Plastic

Premium gym clothes without endocrine disrupting polyester or plastic-based synthetic fibers.

Polyester-Free Gym Clothes

The same styles you love, made with 100% natural fibers like cotton & merino wool.

The Problem

What's wrong with polyester?

Sheds Microplastics

Polyester is literally made of plastic. Which means every time you wear it, it sheds microplastics into your skin.

Contains endocrine disrupting chemicals

What do bleach, formaldehye and BPA have in common? They all could be lurking in your average pair of gym shorts.

Has Potential Fertility Impacts

Sweating in hot plastic coated in chemicals? Bad news for your endocrine an reproductive systems.

Comfortable and Stretchy

"I wanted to switch from polyester but was worried 100% merino wool wouldn't be as comfortable. Was very wrong - shorts are super soft and stretchy - wear them daily to lift"

Here's the problem

You're probably wearing plastic gym clothes.

What do we mean?

Go grab your favorite pair of gym shorts and check the tag.

Let me Guess

Polyester, elastane or spandex, right? But did you know these materials are actually made of plastic?

Ew, Sounds gross.

It is. And plastic-based synthetic fibers have shown to contain a slew of toxic chemicals (like bleach, formaldehyde and even BPA 🤢)
