- Science shows clothing can contain and release PFAS, phthalates, bisphenols, heavy metals, and microplastic fibers. These toxicants can migrate into sweat, absorb through skin, and be inhaled via shed fibers. Synthetic and "functional" fabrics carry higher loads of these additives.
- Laurel recommends clothing made primarily from natural fibers such as organic cotton, linen, mulberry silk, hemp, and wool. For some categories, we also require some meaningful safety certifications.
- Laurel avoids synthetic materials (polyester, nylon) and semi-synthetic materials (rayon, modal, viscose, lyocell), as well as anything marketed as stain-resistant, antimicrobial, or wrinkle-resistant.
- Tip: If you can't overhaul your whole wardrobe at once, prioritize the items closest to your skin for the longest time: underwear, pajamas, and workout clothes.
