Organic cotton shell. Merino wool liner. Zero plastic.
If you're between sizes, size up. More fit details
Expect the liner to feel snug at first
The merino wool liner fits snug out of the bag (mostly around the waist and glutes). This is normal. Give it a workout for the wool to relax and mold to your body. If it feels way too tight on the first try - size up.

Description
The Natural Performance Short
The Quad Short is our take on a natural athletic short, built for the guy who refuses to train in plastic. An organic cotton shell combined with a merino wool compression liner gives you everything synthetic shorts promise, without the microplastics against your skin.
Why Two Layers?
The heavyweight brushed terry shell is 100% organic cotton: soft, durable, and breathable. Underneath, a midweight merino wool liner delivers natural stretch, compression, and moisture-wicking that rivals any synthetic. Two natural fibers, working as a system. No blending, no compromises.
What Makes Merino Different
Merino wool is the superhero of natural fibers. It regulates temperature in heat and cold, resists odor without chemical treatments, and provides real compression and snap-back. That's why we use it where it matters most: directly against your skin during training.
Built for the Workout
- Athletic fit with 4" shell inseam and 6" liner inseam
- Side zipper pockets to secure your phone, keys, and wallet
- Internal drawstrings for a locked-in fit
- Cotton tags, no synthetic labels irritating your skin
- Made with GOTS-certified organic cotton and OEKO-TEX 100 dyes
Pair It
Match with the Only Tee for a clean training look, or try out the Classic Short on rest days when you want something more relaxed.

Common Questions & Misconceptions
Natural fibers are different from synthetics. Here's what you need to know.
Is the liner supportive? Does it ride up?
The liner is a 6" merino jersey under a 4" shell, so it sits below the shell hem and stays there. It is built as a compression liner to hold things in place for higher intensity training and sport. Merino gives the right amount of natural stretch without relying on spandex.
Does merino itch?
Not at this grade. The itch people remember is from coarse wool with a high micron count. This is a fine single jersey merino chosen specifically for next-to-skin wear.
Will cotton get heavy and stay wet during training?
The layer against your skin is merino, which manages moisture incredibly well. It holds up to 30% of its weight in moisture while still feeling dry. On a hard session you will come out feeling drier than you would in synthetics.
Can I run, lift, and train outside in these?
Yes. That's what the 290GSM shell and the 6" liner are for. See the footage above rather than taking the claim on faith.
How do they hold up to repeated washing?
Cold wash, gentle cycle, hang or lay flat to dry, and skip the dryer. Heat is what shortens a merino liner's life. Because merino resists odor you'll wash these less often than a synthetic short, which is a real part of why they last.
I'm between sizes.
Size up. Our shorts run on the smaller side, and the covered elastic waistband with its internal drawstring gives you room to dial the fit in.
What if something's wrong with them?
Money-back guarantee. If you don't like them we refund you and handle the return or exchange, no questions asked. If anything is damaged or defective, we sort it promptly and free of charge.
THE PROBLEM
Most activewear is plastic.
Spun from petroleum & plastic bottles
Traps heat & sweat against your skin
Holds onto odor after every wear
Sheds millions of microplastics
Researchers are still learning what that does to us. We’d rather not be the test subjects.
The Quad Short
100% Natural Fiber Athletic Wear
- No microplastics
- No PFA "forever chemicals"
- No BPA, formaldehyde, or azo dyes
You wear workout clothes to be healthy, but most activewear brands use materials that make you sick. These are 100% natural fiber shorts designed with your health in mind.

FAQ
Organic cotton is cotton grown without synthetic pesticides, fertilizers, or GMOs. It’s farmed in healthier soil, uses far less water than conventional cotton, and produces a fiber that’s softer, stronger, and cleaner against your skin.
We use GOTS-certified organic cotton on most garments, which ensures the entire process from seed to dye house meets strict environmental and safety standards.
Merino wool comes from the Merino sheep, known for producing some of the softest, finest wool fibers in the world. Unlike traditional wool, merino fibers are ⅓ the thickness of a human hair, giving them a luxurious, non-itchy feel.
Merino is naturally breathable, temperature-regulating, moisture-wicking, and resistant to odor. We like to call it nature’s performance fiber, since it is perfect for movement apparel.
Merino wool is uniquely engineered by nature for movement:
- it cools when you’re hot and warms when you’re cold
- it transfers moisture away from the skin
- it resists odor even after repeated wear
- it stretches with the body and springs back
No plastic fiber has replicated this. Merino gives you performance without the petrochemicals.
Traditional wool can be. Merino isn’t.
Merino wool isn't itchy because its fibers are incredibly fine (thin) and flexible, allowing them to bend easily against the skin instead of poking and prickling like coarser, thicker traditional wool fibers.
Measured in microns, merino wool fibers are much smaller (typically 17-21 microns) than standard wool (around 30 microns). If you’ve never worn merino, you’ll feel the difference immediately.
We use OEKO-TEX certified low-impact dyes on all organic cotton and merino fabrics. These dyes are free from harmful chemicals, heavy metals, and known irritants, making them safer for your skin and the environment.
Yes! It’s one of the benefits of natural fiber clothing, as natural fibers are hypoallergenic. Our fabrics are 100% natural and free from polyester, nylon, spandex, and chemical performance coatings, making them much gentler on sensitive skin.
If you’re avoiding petrochemicals, endocrine disruptors, or microplastics, Wayve is aligned with that lifestyle.
Absolutely. Our clothing is designed for movement of all sorts and we carefully select fibers that will withstand these types of activities. Organic cotton and merino wool both perform exceptionally well during movement, and unlike synthetics, they don’t get swampy, shiny, or plasticky as you heat up.
Organic cotton gives a sturdy, natural feel. It’s soft, breathable, and offers a slight stretch.
Merino wool is also quite soft, and actually works to regulate your temperature.
Merino wool is stretchy, but it doesn’t “snap” back like spandex does. It will mold to your body without irritation or that plasticky cling that you get with synthetic fibers.
Our organic cotton pieces may shrink slightly (within 3–5%) on the first wash if dried with heat.
Merino pieces have natural elasticity and return to shape easily when washed, but avoid high heat to preserve the fiber.
For best results, wash cold and hang dry. Your pieces will hold shape, color, and feel for years.
It’s simple:
- wash cold
- use gentle, natural detergent
- avoid fabric softeners
- hang dry to preserve shape and fiber integrity, or tumble dry on low heat
Natural fibers don’t need the same chemical care routine synthetics do. Treat them gently and they’ll last a lifetime.
