Merino Wool Outperforms Polyester. Here's How.
Everything you've been told about performance fabric is backwards. Synthetics need chemical treatments to do what natural fibers do on their own: wick moisture, resist odor, regulate temperature. The Quad Short is proof.
The activewear industry sold you a myth. Here's what's actually going on.
of synthetic "moisture-wicking" fabrics rely on chemical coatings. Known carcinogens off gassing over time.
more bacteria growth on polyester vs. merino wool after the same workout. That's why synthetic shorts stink (literally) and need antimicrobial treatments
of its own weight in moisture. That's how much merino wool absorbs before it even feels wet. Polyester? Less than 1%.
Performance That Comes From the Fiber, Not a Lab
What Real Workouts Feel Like in Natural Fibers
"Noticeable difference in my energy levels"
Got my first full lift in today... felt a noticeable difference in my energy levels... The zipper pockets are nice because you don't have to worry about stuff falling out.
"Great wicking layer with the merino wool"
Great pair of shorts! Been looking for an all natural fibre training short for a while and have got these in black. Super comfortable, great wicking layer with the merino wool and great customer service! Would recommend.
"Pleasantly surprised at how stretchy and wicking the wool liner is"
Great for workouts or as casual fashion. I was pleasantly surprised at how stretchy/wicking the wool liner is.
What Merino Wool Actually Does
Wicks Moisture — Naturally
Merino wool fibers absorb up to 30% of their weight in moisture before feeling wet. No chemical coating required. It pulls sweat away from your skin through the fiber's natural structure.
Regulates Temperature in Both Directions
Merino keeps you cool when it's hot and warm when it's cool. Synthetics trap heat. Merino actively manages it. That's why it's been used by athletes and explorers for centuries.
Resists Odor Without Chemicals
Merino's fiber structure naturally resists bacteria growth - the actual cause of odor. Synthetic liners need antimicrobial treatments that degrade with every wash. Merino's odor resistance is permanent.
290GSM Organic Cotton Shell
The shell provides structure, durability, and breathability. Organic cotton at this weight performs, no plastic needed. Gets softer with every wash while holding its shape.
Zero Synthetic Materials. Period.
Every layer of the Quad Short performs through natural fiber properties, not chemical engineering. You're training to get healthier. Your clothes shouldn't work against that.
Quad Short vs. Polyester Performance Shorts
Performance that comes from the fiber. Not a chemical lab.
Quad Short: Natural Fiber Short
Tested in Real Workouts
"Just as comfortable as synthetics without the downsides"
Got a great workout in with these shorts! Just as comfortable as my synthetic gym shorts without any of the downsides of artificial fabrics. Might have to cop another pair sooner than I thought.
"Insanely hard to find athletic wear not made of polyester — TOP TIER"
These shorts are the best! It's insanely hard to find athletic wear that is not made of polyester and these are TOP TIER. The wool lining is so soft...
"No better feeling than natural fibers against your skin"
There is no better feeling than clean, organic, natural fibers against your skin. These shorts make me happy.
"Maximum range of motion — exactly what I was looking for"
Ultra comfortable, allows for maximum range of motion, exactly what I was looking for.
After 2 years of testing, I can confirm that they don't just keep up - they beat them in every category. The merino wool liner wicks better, manages odor better, and regulates temperature better than any synthetic liner I tested. And it does it without a single chemical treatment.
The activewear industry chose synthetics because they're cheap. Not because they perform better. Once you train in natural fibers, you feel the difference immediately.
