How to Swap to Non-Toxic women's workout clothing:

Here's how to swap to non-toxic women's workout clothing:

What to know about workout clothing

Workout clothes sit directly against your skin for extended periods, often while you sweat. This combination of prolonged skin contact, moisture, and heat can increase how much your skin absorbs from the fabric. That's why the materials your activewear is made of matter more than you might think.

  • Most conventional workout clothing is made entirely from synthetic fabrics that may carry chemical coatings, synthetic dyes, or finishes like PFAS.
  • Pieces worn during high-intensity or long workouts deserve the most attention since heat and sweat increase skin absorption.

Review what you already wear

Check the fabric labels on your current workout clothes. Look at both the materials and any finish or treatment claims. Start with the pieces you wear most often or that cover the most skin.

  • Labels that list 100% polyester, nylon, or similar synthetics with no mention of certifications are worth flagging first.
  • Look for terms like "anti-odor," "moisture-wicking," or "stain-resistant" — these often indicate chemical treatments applied to the fabric.

Get more out of what you already own

Replacing a full workout wardrobe isn't realistic all at once. A few simple habits can help reduce what your skin picks up from the activewear you already have.

  • Wash new workout clothes at least once before wearing them to help remove residual dyes and finishing chemicals.
  • Change out of sweaty workout clothes as soon as you can rather than lounging in them, since prolonged moisture and heat increase absorption.

Choose cleaner workout clothing

Look for activewear made primarily from natural, breathable fibers like organic cotton, hemp, or merino wool. If stretch is needed, a small percentage of elastane or spandex is fine as long as the garment is free from PFAS and other chemical treatments.

  • Prioritize pieces that carry GOTS or OEKO-TEX® certifications, and look for brands that are transparent about their dyes, finishes, and sourcing practices.
