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

Up to 60% of polyester shorts (from major brands) have tested positive for BPA and "forever chemicals".

Has Potential Fertility Impacts

Sweating in hot plastic coated in chemicals? Bad news for your endocrine and reproductive systems.
Polyester free gym clothes

"Finally something that's polyester-free. Shorts just like big brands - but happy they're made without polyester."

Comfortable and Stretchy

"I was worried 100% merino wool wouldn't be comfortable - but I was wrong. Shorts are super soft & stretchy - wear them daily to lift."

No Microplastics

"After learning about microplastics in athletic clothing I tried to find a good brand without them. Happy I found Ryker. Super comfortable - I have 2 pairs of shorts & boxers."

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 🤢)
