"Ryker's shorts are extremely comfortable and I actually wear them more outside of the gym. I find them so comfortable and usually wear them around the house or when talking a walk. Such a great alternative to polyester shorts."

"I was honestly shocked when I first tried on the gym shorts. Most natural shorts I've tried are just ok, but these actually feel like regular gym shorts but somehow are 100% organic cotton. Highly recommend for exercise or even just lounging around"

What’s wrong with polyester?
made of
toxic plastic
Polyester is PLASTIC. You likely try to avoid plastic - so do you really want to wear it?
Endocrine disrupting chemcials
Polyester can have endocrine disrupting chemicals - which can drop your T levels.
Sheds Microplastics
When you wear polyester, microplastics can shed into your skin and the air around you.
BPA and "Forever Chemicals"
These "forever chemicals" can leech into our water supply (and your skin).
Formaldehyde & antimony
Formaldehyde? You mean the toxic chemical they use on corpses? Yup, we do.
Potential Fertility Impacts
Endocrine disruptors are one reason men's sperm counts are down 50% since 1970.

FREQUENTLY ASKED QUESTIONS
What's the problem with polyester?
Polyester is literally made of plastic. This means when you wear it & wash it, it can leach microplastics in the water supply (and your skin). It's also chock full of toxic chemicals (like BPA, bleach and formaldehyde). If you're worried about plastic and avoid things like plastic bottles and tupperware, you should avoid polyester.
Why organic cotton?
Organic cotton is the perfect natural fiber. It's free of toxic pesticides and harmful synthetic chemicals. It's also naturally soft & highly breathable - perfect for activewear. And the best part? We specifically weave our organic cotton fibers to keep their natural stretch - make them ideal for gym shorts.
Do they fit & function like normal gym shorts?
Yes! We're not reinventing the wheel here - just making it healthier for you. Ryker shorts fit just like the big brands (Lulu, Vuori, Gymshark, etc.) and function just the same. You can lift in them, run in them, grapple in them - whatever you do, you can do in Ryker.
How do I care for my shorts?
We recommend a cold wash on a low setting. We recommend hanging to dry. But if you do put them in the dryer, we recommend a low setting.
Do you offer returns & exchanges?
Of course - customer satisfaction is our #1 priority. We offer a 30-day return and exchange policy.
