5 Reasons to Ditch Your Toxic Polyester Gym Shorts
And the best alternative to choose...
MICROPLASTICS
1. Polyester Sheds Microplastics
Polyester = plastic. Which means you're practically wearing saran wrap.
Every wash & wear, polyester sheds microplastics - directly onto your skin.

HAMRFUL CHEMICALS
2. Polyester Often Contains Toxic Chemicals
You know the nasty chemicals in plastic bottles & tupperware?
Polyester often has those too. We're talking BPA and even "Forever Chemicals".
One shocking study found that 100+ activewear brands contained high levels of endocrine disrupting BPA - some even have 40x the legal limit!

CHEMICAL LEACHING
3. Your Body Can Absorb These Chemicals - Especially When Sweating
These chemicals don't just stay on the fabric either.
Research shows that heat & sweat can cause chemicals like BPA in clothing to leach directly into your skin.
Not exactly what you want during your workout.

HORMONE & FERTILITY IMPACTS
4. These Chemicals May Have Hormone & Fertility Impacts
These chemicals aren't harmless.
Chemicals in polyester - such as BPA and PFAS - are linked to hormone disruption & fertility impacts.
One shocking study showed wearing polyester underwear made men azoospermic - meaning their sperm count dropped to zero. Not only that - it caused their balls to shrink too.

OPTIMIZE WHAT MAKES SENSE
5. You Optimize Everything Else - Shouldn't You Optimize This?
You spend $200 on supplements. You track your Whoop data. And you avoid plastic elsewhere.
Why wrap yourself in it when you're hot & sweaty?
Make the simple, one time switch - and stop wrapping yourself in plastic.

I optimize everything else. This was my one blind spot.
"I spend $600/month on supplements, recovery, and bloodwork. I track every input that goes into my body. Then I realized I was spending 4 hours a day training in petroleum-based plastic that's been linked to hormone disruption. Once I saw the data on polyester and endocrine disruptors, I couldn't unsee it. Switched to Ryker, and I won't go back. These are now a non-negotiable in my protocol."

I looked at the research. The decision was obvious.
"I don't buy anything based on marketing alone. I looked at the actual studies on polyester, microplastics, and BPA - and the data is hard to argue with. Ryker's third-party lab results showing zero endocrine disruptors sealed it for me. The Merino liner is genuinely more comfortable than any synthetic I've worn. These are the only shorts I train in now."

The last gap in my health stack.
"Eight Sleep, WHOOP, my sauna - I've invested in all of it. But I was still training in polyester shorts that shed microplastics. It's absurd when you think about it. Ryker closed the last gap. The fit is identical to Lululemon, the Merino liner handles sweat better than any synthetic, and I'm not absorbing endocrine disruptors through my skin for two hours a day. Should've done this years ago."
Frequently Asked Questions
What materials do you use?
We exclusively use natural fabrics like 100% organic cotton & Merino wool. No polyester or plastic based fabrics. These materials allow us to avoid microplastics & toxic chemicals.
Won't wool be hot?
Merino wool is NOT your grandma's wool sweat. Merino wool is naturally temp regulating - it keeps you cool when you're hot and hot when you're cold. It's why hikers & the military have used it for decades.
Our customers even say our shorts are comfortable in the Texas heat!
Why is it more expensive than some other synthetic brands?
Because we don't compromise. Because we only use high quality, organic fabrics like 100% organic cotton & Merino wool, our product costs are substantially higher than big brands who sell cheap materials (polyester) at a premium price.
Additionally, we only partner with ethical manufacturers who maintain GOTS & OEKO-TEX Standard 100 certifications, pay their workers a fair wage, and maintain safe conditions for their staff.
Last thing - we're proud that we're still priced competitively to premium brands like Lululemon, Vuori, Rhone and Ten Thousand - 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 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.
Are your clothes 3rd party tested?
Yes. Not only do we rely on regular factory audits from the governing bodies of GOTS & OEKO-TEX Standard 100, but we also independently test our fabrics & end garments.
You can see our latest test here. Completely free of BPA, PFAS, and phthalates.
What size should I get / will your products shrink?
For Apex shorts (built in liner), we recommend sizing down. If you're a large in Lulu, we recommend ordering a medium.
We have specifically sized our garments this way.
We always recommend washing on the most gentle setting available + laying flat to dry to reduce shrinkage.
What's the return policy?
We offer a 90 day return policy. As long as the garment is unused (meaning, you don't wear it several times and then decide to return), we will accept your return.
We want happy customers - not annoyed customers. So we're pretty generous here.
Done wearing toxic plastic shorts?
Make the risk free switch to Ryker.
90-day no hassle returns
Don't love your Ryker shorts? Return quickly and easily with a 90 day money back guarantee.
