Below average — consider alternatives

This fabric scores low on quality. It may pill, wear out quickly, or not feel great against skin. And when it does wear out, it'll sit in a landfill for decades. Look for higher-rated options.

🚨

Acrylic sheds more microfibers than any other fabric — up to 730,000 per wash. It's the worst offender for microplastic pollution.

🌍

This fabric will take 200+ years to decompose. That means a shirt you buy today will still exist in the year 2226.

🧺
