Understanding Your Wove Score

The Wove Score is an A+ to F grade that tells you how healthy and sustainable a clothing item is, based on its fabric composition, microplastic shedding risk, PFAS chemical concerns, and overall environmental impact. A higher score means cleaner, more natural materials.

PFAS (per- and polyfluoroalkyl substances) are synthetic "forever chemicals" used to make clothing water-resistant and stain-proof. They don't break down in the environment or in the body and have been linked to various health concerns. Wove flags garments that are likely to contain PFAS based on fabric treatments and material type.

Microplastics are tiny plastic particles — often invisible to the naked eye — shed from synthetic fabrics like polyester, nylon, and acrylic every time they're washed. These particles enter waterways, ocean ecosystems, and have been detected in human blood, lungs, and breast milk. Clothing is one of the biggest sources of microplastic pollution.

Natural fibers score highest: organic cotton, linen, wool, silk, and hemp. These materials don't shed microplastics, are biodegradable, and don't require synthetic chemical treatments. Fabrics like polyester, nylon, and acrylic score lowest due to high microplastic shedding and chemical concerns. Items like underwear and base layers are where natural fibers matter most, since they're in direct contact with skin all day.

Yes. Wove is free to download and free to use. We do not accept advertising, brand partnerships, or sponsored placements — so every score you see is genuinely independent. We'll never show you a result that a brand paid for.

You can scan a product by pasting a URL, uploading a photo, or entering a product description. Wove reads the fabric content information and runs it through our scoring model — instantly breaking down natural vs synthetic fiber percentages, microplastic shedding risk, PFAS likelihood, and sustainability rating. You can also scan a clothing label directly using the app's camera.
