Frequently asked questions.

What is Cotton On clothing made of?

Based on our analysis of 50 Cotton On products, the average garment is 62.5% natural fibre. The most common single fibre is Cotton (in 56% of products). The remaining material is typically synthetic — polyester, polyamide, or acrylic.

Is Cotton On cotton?

Sometimes — cotton appears in 56% of the 50 Cotton On products we analyzed, but it's usually blended with synthetics. Only 38% of items are nearly all-natural (95%+ natural fibre), so check the composition before assuming a piece is pure cotton.

Is Cotton On 100% cotton?

Some pieces are. Of the 50 Cotton On products we analyzed, 16 are 100% cotton (or near-pure, 95%+) — that's 32.0% of the catalog. The rest are blends.

How much polyester does Cotton On use?

18% of Cotton On products are polyester-heavy, meaning polyester makes up 50% or more of the garment. This is below average for fast fashion retailers.

Is Cotton On mostly synthetic?

18% of Cotton On products are polyester-heavy (50%+ polyester). Average natural fibre content is 62.5%, so the rest of the catalog is mostly natural-led.

Does Cotton On use natural fabrics?

Is Cotton On sustainable in terms of fabric?

Fabric composition is one factor in sustainability. With an average of 62.5% natural fibre, Cotton On is better than many competitors on this measure. Natural fibres generally biodegrade and shed fewer microplastics than synthetics.

Methodology: We analyzed 50 Cotton Onproduct pages, extracting the fabric composition listed by the retailer. Products are categorized by name keywords.
