Recycled Polyester vs. Recycled Nylon: A Fabric Guide to Sustainable Activewear

Walk through any activewear collection today and you'll see the word "recycled" on almost every tag. But recycled polyester and recycled nylon are not the same material, they're not sourced the same way, and they're not equally good at the same job. If you've ever wondered why your leggings and your tank top feel completely different, or whether "recycled" actually means "sustainable," here's the honest breakdown.

What is recycled polyester?

Recycled polyester — often labeled rPET — is made by collecting post-consumer plastic, most commonly clear plastic bottles, cleaning it, melting it down, and re-spinning it into new polyester fiber. The chemistry is identical to virgin polyester once it's respun, which is why recycled polyester performs the same way: quick-drying, breathable, and resistant to wrinkling. It's a natural fit for tanks, tees, and lightweight layers where moisture-wicking and airflow matter more than heavy-duty stretch.

What is recycled nylon?

Recycled nylon is typically sourced from a different waste stream entirely — pre-consumer fabric scraps, industrial nylon waste, and in some cases discarded fishing nets and carpet fiber, reprocessed back into a usable yarn. Compared to recycled polyester, recycled nylon tends to have better stretch recovery and a smoother, softer hand feel, which is exactly why it shows up in leggings, sports bras, and anything that needs to hold compression through a workout and still bounce back afterward. Zola's Revive 7/8 High-Waist Leggings, for example, are cut from 75% recycled nylon and 25% spandex specifically for that reason.

So which one is "more sustainable"?

Neither one is automatically the better answer — it depends what you're optimizing for. Both processes use meaningfully less energy and fewer virgin petroleum inputs than producing new polyester or nylon from scratch, and both divert real waste (bottles, nets, fabric scraps) out of landfills and oceans. But recycling doesn't erase every tradeoff: neither recycled polyester nor recycled nylon is biodegradable, and both are still synthetic fibers that can shed microplastic fibers in the wash, same as their virgin counterparts. "Recycled" is a genuine improvement over virgin synthetic fabric — it isn't a free pass to stop thinking about impact.

One easy habit that actually helps

If you want to cut down on microfiber shedding from any synthetic activewear — recycled or not — wash it in a mesh filter bag, use cold water, and skip the dryer when you can. It's a small habit that measurably reduces what ends up in the water system, regardless of which fabric is in your closet.

How Zola uses each

We build with recycled materials across the line — recycled polyester where breathability and quick-dry performance matter most, recycled nylon where compression, stretch recovery, and a softer hand feel matter more, like our leggings and biker shorts. It's part of why our Sustainability page reports over 60% recycled material use across the collection. If you're shopping by fabric, our women's and men's collections list the fiber content on every product page.
