"Ryker's shorts are an absolutely elite alternative to polyester plastic shorts. They are super lightweight and silky smooth. Would highly recommend for anybody who is looking to ditch their polyester shorts but still wants that stretchy feel that you need in the gym."

"Ryker's built-in-liner shorts are extremely comfortable. Not comparable to anything you’ve ever worn before, and don’t even feel you’re wearing a liner. Very comfortable. Honestly my new favorite pair of gym 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?
Toxic chemicals
Polyester may contain toxic chemicals - which are used to make & coat the clothes.
Sheds Microplastics
When you wear polyester, microplastics can shed from the clothes into 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.

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.
Why Merino wool liner?
Gym shorts made with wool? We know what you're thinking. But Merino wool is different. It's naturally stretchy, odor resistant, and temperature regulating. And its ultrafine fibers means it doesn't itch like normal wool. This makes it perfect for built-in compression liner.
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.
Do you offer returns & exchanges?
Of course - customer satisfaction is our #1 priority. We offer a 30-day return and exchange policy.
