Once you see the comparison, the choice is obviouss.
1. Made of 100% natural fibers - not plastic synthetics
Most “performance” shorts are made from plastic. Ryker shorts are made from organic cotton and Merino wool, no plastic-based fabrics. You spend thousands on supplements, recovery, and clean food. Why sweat in plastic?
2. Third Party Tested - No Hormone Disrupting Chemicals
Big Brand plastic fabrics often contain endocrine disruptors like BPA and PFAs - these chemicals have been shown to impact testosterone and fertility.
Not Ryker. We're third party tested - absolutely ZERO BPA, PFAS or Phthalates. See our full lab test here.
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. The Early Adopters Have Already Switched.
Over 50,000 men have already made the switch from synthetic to natural. Among them: tech founders, engineers, and experts ahead of the curve.
Biohacker Ben Greenfield calls them "the only shorts I want to wear". You never wait for the mainstream to catch up, why start now?

Great product!
Been eliminating plastic as much as possible and just started with doing the same with my activewear. Came across these Ryker shorts and not disappointed at all. Sized up one size as recommend to a large as I normally wear medium and the fit is great. The quality also surprised me as I wasn’t expecting much due to these being organic cotton, but they seem pretty durable. I prefer these over my Nero ones as well. Quality on these seem to be better.
Just try them once and you won’t look any further. Hands down, the apex shorts are the most comfortable shorts I’ve ever worn. They’re great for workouts, lounging, sleeping.. honestly, I have a hard time not wearing these everywhere!! I was looking for something without synthetic materials and just assumed I’d be sacrificing health for comfort. The reviews are spot on. The merino wool Ryker uses does not itch at all!!
This is the second occasion I have worn them, and unfortunately, the zipper on the side pocket has already broken. They are exceptionally comfortable, and I am hopeful that this is an isolated incident. I will likely consider purchasing another pair. Regrettably, due to having worn them, they are no longer eligible for return.
Wildly comfortable. I haven't noticed any increase in temperature (compared to other shorts/underwear) when I work out with them. Super happy especially because they are free from plastics and toxins. Trying to transition all my underwear and workout apparel to these slowly since they are a premium price.

Knew about microplastics years ago. Shouldn't have waited so long to switch.
"Have obviously known about microplastics for years. I tried natural brands but all either fit & felt terribly or we're still blended with a pretty solid amount of synthetics. Ryker is a great balance - natural fibers + actually fits & performs like Lulus. Have gotten 3 pairs."

Love them - and shocked big brands still haven't come around.
"I've been skeptical of polyester for a while — the microplastics data, the BPA studies, all of it. Looked at every 'sustainable' brand out there and they were all still using plastic and calling it eco-friendly. Ryker is the only one actually doing it right. Great fit, great materials, and the lab results are published. This is where the whole industry is headed — they're just early."

I'm pretty early on most health stuff. These are legit.
I was talking about seed oils and microplastics before most people knew what they were. So I'm pumped I finally found these - 100% natural fibers + lab tested to be BPA free. They fit like Lululemon, the merino liner is better than any synthetic I've tried, and I don't have to think about what's absorbing into my skin. Easy switch.

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'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 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.
