Frequently Asked Questions

Is all COS polyester 100%?

No. We found 8 COS products that are 100% polyester (or near-pure, 95%+) — that's only 4.2% of their catalog. The rest of COS's polyester items are blended with other fibres.

Where can I buy 100% polyester clothing from COS?

Every product on this page links directly to COS's website. We sort by polyester percentage, so the purest items appear first.

Why does COS blend polyester with other fibres?

Blends are cheaper to produce and can add stretch, durability, or wrinkle resistance. If you want pure polyester — which biodegrades and sheds fewer microplastics — stick to the 8 items listed below.
