Frequently Asked Questions
Is all COS cotton 100%?
No. We found 5 COS products that are 100% cotton (or near-pure, 95%+) — that's only 10.6% of their catalog. The rest of COS's cotton items are blended with other fibres.
Where can I buy 100% cotton clothing from COS?
Every product on this page links directly to COS's website. We sort by cotton percentage, so the purest items appear first.
Why does COS blend cotton with other fibres?
Blends are cheaper to produce and can add stretch, durability, or wrinkle resistance. If you want pure cotton — which biodegrades and sheds fewer microplastics — stick to the 5 items listed below.
