Finding sustainable, non-toxic activewear can feel like a workout in itself. Between hidden synthetics, chemical finishes, and greenwashing, it’s tough to know what’s truly safe for your skin and the planet. While finding 100% plastic-free workout wear is still a challenge, there are a few brands getting very close - and many others making meaningful strides with safer fabrics, non-toxic dyes, and low-impact production.

Prioritizing Safer, Skin-Friendly Materials
Most activewear on the market is made with polyester, nylon, or spandex - materials derived from fossil fuels and often treated with harmful chemicals. But some brands are swapping these out for organic cotton, hemp, and TENCEL™ - offering breathable, soft, and safer alternatives for your skin. While performance demands still require some stretch (like elastane), these brands are minimizing synthetics wherever possible and opting for Oeko-Tex or GOTS-certified fabrics that skip the toxins.
Brands Moving Toward Plastic-Free Performance
Completely plastic-free activewear is rare, but a few brands are getting impressively close. Look for small-batch labels using natural rubber, plant-based elastics, or organic cotton blends that prioritize skin safety. While these pieces may not have the same stretch as traditional leggings, they’re perfect for low-impact movement like yoga, pilates, or everyday wear - and they won’t leave microplastics behind.
Say No to “Forever Chemicals”
PFAS (per- and polyfluoroalkyl substances), often called “forever chemicals,” are sometimes used in activewear for water resistance or stain repellency - but they come with serious health and environmental concerns. Linked to hormone disruption, immune issues, and even cancer, PFAS have no place in our everyday wear. Thankfully, more brands are now pledging to be PFAS-free, ensuring your workout gear doesn’t come at the cost of your long-term health. Always check labels or brand commitments, and prioritize pieces that explicitly state they are free from these harmful chemicals.
