What’s wrong with polyester?

A tree within a circular border, resembling a family tree or organizational chart.

Literally Made of Plastic

Polyester is PLASTIC. Every time you wear polyester, millions of microplastics shed from the clothes onto your skin and into the air around you.

Toxic Clothing Dyes

Conventional clothing dyes contain petroleum derived byproducts - which can irritate your skin and are linked to health effects.

BPA and Phthalates

A shocking study found that 100+ activewear brands contained high levels of endocrine disrupting BPA - some even have 40x the legal limit!

PFAS and "Forever Chemicals"

Your "moisture wicking" polyester shorts? Often coated in toxic "forever chemicals" like PFAs - which are linked to reproductive problems.

Potential fertility impacts

A groundbreaking study showed wearing polyester underwear made men azoospermic - meaning their sperm count dropped to zero.

Formaldehyde

Many conventional fabric treatments contain high levels of formaldehyde - which can off gas from the fabric.

Our Solution

Made of Natural Fibers

We use 100% organic cotton & 100% Merino wool - no polyester or plastic-based fabrics.

Certified Non-Toxic

Our organic cotton is GOTS certified and our suppliers hold OEKO-TEX Standard 100 certifications, ensuring no harmful chemicals commonly found in traditional activewear.

Breathable & Odorless

Our organic cotton is highly breathable and our Merino wool naturally resists bacteria growth, so you can wear them longer and wash them less.

Athletic Fit & Feel

Our shorts don't fit like some nerdy health product. They have the same exact "activewear" fit you need - without the plastic fabrics.

3rd Party Tested

Not only do we rely on third party certifications, we independently test all of our fabrics - they're completely free of BPA, PFAS, and hormone disruptors.

Super Soft & Comfortable

We use superfine organic cotton & Merino wool - ensuring the softness and comfort you need.

I looked everywhere for organic cotton gym shorts - pumped I finally found them

Been on the hunt for organic cotton gym shorts for some time after I learned my polyester ones were just plastic. Couldn't find any big brand with them & then found Ryker - love them.

Jason M., Los Angeles

Throwing out my Lulus now...

I was skeptical but these shorts literally fit exactly like my Lulu shorts but they're made of 100% organic cotton. Exactly what I'm looking for - great fit & material. Tossing my Lulus and buying more.

Connor B., New York City

Happy to not be wearing plastic in the gym or sauna anymore...

Yes they're expensive, but I'm happy to not be wearing plastic to the gym and in the sauna anymore. They're also surprisingly stretchy - very different than many other natural brands.
