1. Third Party Tested - No Hormone Disrupting Chemicals
We don't just say "eco-friendly" and "non-toxic" - we have the proof to back it up. We 3rd party test all Ryker fabrics in accredited labs. Every result? Absolutely ZERO BPA, PFAS, and phthalates.
We're all about transparency - see our full report here.
2. Made of 100% natural fibers - not plastic synthetics
Hate brands that claim to be sustainable yet are loaded with "recycled polyester" (as if that's any better!?).
That's not us. Just natural fabrics - 100% organic cotton & Merino wool. Fabrics from nature, not from a lab.
3. Our Merino Liner Naturally Breathes & Wicks Sweat - Keeping You Smelling fresh.
Merino wool wicks moisture away more effectively than polyester. It's also naturally antimicrobial, which means it controls odor.
The result: no clammy feeling and no stink after a hard session. Wear them for a two-hour workout, and then again the next day. They'll still be fresh.
4. Fits just like big brands. Without the plastic.
Ryker fit & perform exactly like your Lulus - same athletic cut & range of motion.
This isn't a compromise. It's the same performance fit you expect — built with materials that aren't working against your health.

5. Practitioners and Health Experts Have Already Made the Switch
Over 50,000 men have already made the switch from synthetic to natural. Among them: founders, CEOs, and managing directors - people who need their edge.
Expert biohacker Ben Greenfield calls them "the only shorts I want to wear". You know more about endocrine disruptors than anyone - it's time to start living it.

Why Practitioners Are Making the Switch...
MH
Dr. Travis W.
Naturopath
Portland, OR
I can't tell patients to reduce exposure and then train in polyester.
"I spend my days helping patients identify and eliminate sources of endocrine disruption. When I realized my own gym clothes were a source of BPA and microplastic exposure, the contradiction was impossible to ignore. Ryker is the only activewear I've found that meets the standard I set for my patients. I recommend it in practice now."

Dr. Chris S.
Chiropractor
Los Angeles
The lab results convinced me. The comfort kept me.
"I'm trained to evaluate evidence. Ryker's third-party lab results showing zero BPA, PFAS, and phthalates were exactly what I needed to see. The Merino liner is genuinely more comfortable than any synthetic I've worn. I wear these to the clinic, to the gym, and on weekends."

This is what I've been recommending to clients. It finally exists.
"I teach a course on reducing environmental toxin exposure. Clothing has always been the gap — I could never find activewear that met the standard. Ryker fills it completely. 100% natural fibers, third-party tested, published results. I've already referred dozens of clients and students."
Trusted by Health Practitioners and Leading Biohackers

"Ryker is changing the game with gym clothes. What I like is that Ryker's shorts still fit like gym shorts & don't feel like some nerdy "health product" - but they're toxin free, 3rd party tested, and made of 100% natural fabrics. They're now the only shorts I want to wear."

Frequently Asked Questions
How do these compare to synthetic brands like Lulu?
Our shorts fit & perform exactly like your Lulus - same athletic cut & range of motion. We've also meticulously designed them with a specialized knit & weave to give them stretch without elastane blends.
The difference is what they're made of. Big brands are made of polyester & nylon (petroleum based plastic). We use 100% organic cotton & Merino wool.
Same fit and function, zero plastic fabrics, zero endocrine disruptors. Most customers who switch tell us the merino liner actually handles moisture and odor better than any synthetic they've worn.
What dyes do you use?
We use water based fiber reactive dyes that comply with GOTS & OEKO-TEX Standard 100 class 1 standards.
They're independently tested for heavy metals & other toxins commonly found in the apparel industry.
What's the science behind the harms of polyester?
We get it - health claims can often feel like noise. But here's what the research actually shows: peer-reviewed studies have linked polyester undergarments to reduced sperm count, and independent testing has found BPA levels in major activewear brands at up to 40x the legal safety limit. PFAS - classified as 'forever chemicals' by the EPA — are commonly used in moisture-wicking treatments on synthetic fabrics.
Chemicals like BPA and PFAS have been shown to be endocrine disruptors that can impact testosterone and fertility - even at small levels of exposure.
This is why we publish our third-party lab results showing zero BPA, zero PFAS, and zero phthalates in our gear. You can view them here.
Why is it $99?
Organic cotton and merino wool cost substantially more than petroleum-based polyester — because they're not derived from plastic.
Most premium activewear brands charge $70-100 for shorts made from materials that cost a fraction of what ours do. We charge $99 for shorts made from certified organic, independently lab-tested natural fibers. Most of our customers spend more than $99/month on supplements alone. Our shorts are a one-time investment in removing a daily source of endocrine disruptor exposure.
We're proud that we're still priced competitively to premium brands like Lululemon, Vuori, and Rhone - despite using high quality, 100% natural materials.
What are GOTS & OEKO-TEX Standard 100?
GOTS is the Global Organic Textile Standard. It means our cotton has been grown & processed without the synthetic pesticides or toxic chemicals (like formaldehyde), commonly found in conventional cotton.
OEKO-TEX Standard 100 means all of our fibers, fabrics, and dyes have been 3rd party tested for a variety of toxic substances - including BPA, PFAS and other endocrine disruptors. When you wear Ryker, you can be confident you're only wearing the best.
What size should I get / will your products shrink?
We almost recommend customers "size up" from whatever they wear in synthetic brands. For example, if you're a medium in Lulu shorts, opt for a large in Ryker.
This is because our gear tends to run a bit small + shrinks ~5% in the wash. This is inherent to a high quality natural fiber.
"Pre-shrunk" cotton is often treated with harmful chemicals to make it that way - and that's not what we're about.
We always recommend washing on the most gentle setting available + laying flat to dry to reduce shrinkage.
What's the return policy?
90-day returns on unworn products. No questions asked. We want you to be confident in the purchase, and we stand behind the product. If it doesn't work for you, send it back.
