Polyester Checker

Instantly checks if a clothing item contains polyester

Most clothing sites don't make it easy to know what you're actually buying. The fabric content is buried in a spec table, written in small print, or listed as "See product details" with no details. You find out it's 78% polyester after it arrives and feels like a plastic bag. Polyester Checker fixes that. It reads the product page you're on and surfaces the fabric composition immediately, so you know what something is made of before you buy it. No searching. No squinting at fine print. Click the extension, see the materials. It works across clothing sites — fast fashion, boutique brands, department stores, outdoor gear, activewear. Wherever fabric content is listed on a page, the extension finds it. If you're trying to avoid synthetics, build a natural-fiber wardrobe, reduce microplastic shedding from your laundry, or just make more informed purchases, this is the tool that was missing. Stores have filters for color, size, and price. None of them let you filter by what the clothes are actually made of. Now you can check yourself, on any site, in one click. Free to install. No account. No data collected.
