WHY WE STARTED
HE WAS TIRED OF TOXIC. SO HE BUILT SOMETHING BETTER.
Garrett did everything right. He trained hard, slept 8 hours, and optimized his diet. But he realized there was blind spot - he was training in plastic.
He looked into the research - and was shocked. Plastic clothes. Loaded with PFAS. Chemicals leaching into his skin during gym & sauna sessions. Chemicals that were proven to disrupt hormones. Not good.
"I optimized everything else. Even small things - like seed oils and toxic personal care products. But I was training in plastic? It didn't make sense. I wanted to make something better."
Garrett, Founder of Ryker Clothing
He didn't have fashion experience. So he went to the source: a single cotton field in Turkey, growing certified organic cotton. Then he spent months on the knit itself – engineering natural stretch into the fabric so it never needs a gram of elastane. The same fit & function as the big brands – without the plastics.

The Problem with poly
4 simple reasons
to ditch polyester.
Polyester = plastic. Do you really want to wear plastic?
MICROPLASTICS
Polyester = Plastic
Polyester is literally just a type of plastic.
Often the same type of plastic that water bottles are made of!
If you avoid those, why wrap your skin in it?

TOXIC CHEMICALS
Polyester Often Contains Toxins
A shocking study found that 100+ activewear brands contained high levels of BPA - some even have 40x the legal limit!
BPA can mess with your testosterone.
And it's been shown the leach through skin contact!

FERTILITY
Potential Fertility Impacts
A groundbreaking 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.

SWEAT & STINK
Polyester Traps Heat & Bacteria - Making You Stink
Polyester is a breeding ground for bacteria.
It traps sweat – causing bacteria to buildup – which leads to smelly shirts.
Every wonder why your shorts STINK after one workout? This is why!

FIT & FEEL
Fits just like Lulu
Not a potato sack
The problem with most 100% cotton tees? They fit like a box and feel like a bedsheet. We didn't want that – so we built it to fit like the big brands.

Cut Like Big Brands, Not Vintage Cotton
Our tees fit exactly like the shirts you already own – athletic through the arms and shoulders, easy through the midsection. Not boxy vintage cotton.

We engineered a special knit that builds natural stretch into 100% cotton — zero elastane, zero spandex. It moves when you move, then snaps back.
3
Feels Like Tech Fabric. Isn't.

Frequently Asked Questions
What's the problem with polyester?
They're both plastic. Polyester is made from the same material as water bottles, and elastane (aka spandex/Lycra) is a synthetic polymer. Studies have found activewear containing BPA at up to 40x legal limits, plus PFAS "forever chemicals" – and both can absorb through skin, especially when you're hot and sweaty. Even most "cotton" tees sneak 5–10% elastane into the blend. Ours has zero.
Won't 100% cotton be stiff and boxy?
That's exactly the problem we obsessed over. We engineered a special knit that builds natural stretch directly into the fabric – no elastane required. Combined with an athletic cut modeled on the big brands, it fits and moves like your favorite Lulu or Nike tee. Not like a vintage boxy cotton shirt.
What materials do you use?
100% GOTS-certified organic cotton. All of it grown in a single field in Turkey – which means total traceability and zero mystery inputs. No polyester, no elastane, no nylon, no blends. Ever.
Why is it more expensive than some other cotton tees?
Single-field organic cotton, a specialized stretch knit, GOTS + OEKO-TEX certification, and third-party chemical testing on our products cost more than pumping out poly-blend tees in a mega-factory. You're paying for what's not in the shirt.
What are GOTS & OEKO-TEX Standard 100?
GOTS (Global Organic Textile Standard) is the world's leading certification for organic textiles – it covers everything from how the cotton is grown to how the fabric is processed. OEKO-TEX Standard 100 independently tests the finished fabric for harmful substances. Our tees carry both, and we third-party test on top of that.
What dyes do you use?
Only GOTS-approved, non-toxic dyes – free of heavy metals, AZO compounds, and formaldehyde. Verified by our OEKO-TEX Standard 100 certification and third-party testing.
Are your clothes 3rd party tested?
Yes. Every product is independently tested for PFAS, BPA, and phthalates – and we publish the results. Zero detected. See the report HERE.
How does it fit? What size should I get?
Athletic through the arms and shoulders, relaxed through the midsection, with a curved hem. It runs large out of the box and shrinks to a fitted cut after wash + dry. If you wear LARGE in Nike/Lulu/Gymshark/Vuori, take a Ryker MEDIUM. Prefer a looser fit? Stay true to size.
