TL;DR: Three separate fabric callouts on one product page, and every one of them is plastic. Even the pocket bags. The Quad Short is 100% organic cotton over 100% merino wool with zip side pockets, at $90.

What's actually in each
Lululemon Pace Breaker Short:
- Body: 86% recycled polyester, 14% elastane
- Liner: 82% polyester, 18% elastane
- Pockets: 89% polyester, 11% Lycra elastane
Wayve Quad Short:
- Shell: 100% organic cotton, 290GSM brushed terry
- Liner: 100% merino wool, 165GSM jersey knit
- Trims: covered elastane at the waistband, cotton drawstring, cotton brand tag, cotton care and material labels
The pockets are the tell. Lululemon publishes a separate composition for the pocket bags — 89% polyester, 11% Lycra. That's more disclosure than most brands offer, and what it reveals is that no component of this short, down to the bag your phone sits in, is anything but synthetic.
Microplastics
Synthetic fabric sheds microplastic fibers through wear and washing — recycled polyester exactly as much as virgin. Recycling changes where the plastic came from, not what comes off it in your machine.
Organic cotton and merino wool shed no plastic, because there isn't any in the fabric.
Dyes and chemical inputs
The Quad Short uses OEKO-TEX Standard 100 low-impact dyes, and the GOTS certification on the cotton prohibits azo dyes releasing carcinogenic amines, formaldehyde, chlorine bleach and heavy metals as chemical inputs at every processing stage. Since 1 January 2024, Standard 100 has also carried a general PFAS ban, assessed by total fluorine to a 100 mg/kg limit.
Lululemon publishes no equivalent standard for this product, so there's no public answer to what's used in its dyeing and finishing.
Odor, performance and end of life
Odor. Polyester traps odor — the fiber's best-known weakness, and the reason synthetic activewear so often carries an antimicrobial finish. Merino resists odor as a property of the fiber. Nothing is applied to the Quad Short.
Breathability. Natural fibers move air and moisture without engineering. Synthetics need construction and finishes to approximate it.
Pockets. The Quad Short has zip side pockets — uncommon in this category, and the difference between running with your phone and leaving it behind.
End of life. Cotton and wool are cellulose and protein fibers; they break down. Polyester and elastane don't biodegrade in any meaningful timeframe — they fragment into smaller pieces of the same plastic.
The verdict
Buy the Lululemon Pace Breaker Short if synthetic fabric doesn't concern you. Lululemon has spent twenty-five years refining this fit across three inseams and dozens of colourways, and you can try it on in a store today. The Pace Breaker is a well-made short.
Buy the Wayve Quad Short if you'd rather the thing against your skin for two hours a day not be plastic — no microplastic shedding, no chemical finishes, certified low-impact dyes, odor resistance from merino wool, zip side pockets, and a garment that biodegrades.
One honest trade: for very high-output endurance work in heat, polyester dries faster. For training, lifting, everyday wear and most running, natural fiber is the better garment.

FAQ
What is the Lululemon Pace Breaker Short made of?
Body: 86% recycled polyester, 14% elastane. Liner: 82% polyester, 18% elastane. Pockets: 89% polyester, 11% Lycra elastane.
Is there a natural fiber alternative to the Pace Breaker Short?
Yes — the Wayve Quad Short at $90, a 100% organic cotton shell over a 100% merino wool liner, with zip side pockets and no synthetic fabric.
Does the Lululemon short shed microplastics?
Yes. All synthetic fabric sheds microplastic fibers during wear and washing, recycled polyester included.
Which is better for sweat and odor?
The Quad Short, on mechanism. Merino resists odor because of what the fiber is; polyester traps it and needs a finish applied to compensate.
Does the Quad Short have pockets?
Yes — zip side pockets, uncommon among natural fiber training shorts.
Is the Lululemon short biodegradable?
No. Polyester and elastane fragment rather than break down. Organic cotton and merino wool biodegrade.
