Frequently asked questions.
What is Madewell clothing made of?
Based on our analysis of 456 Madewell products, the average garment is 86.9% natural fibre. The most common single fibre is Cotton (in 65.8% of products). The remaining material is typically synthetic — polyester, polyamide, or acrylic.
Is Madewell cotton?
Sometimes — cotton appears in 65.8% of the 456 Madewell products we analyzed, but it's usually blended with synthetics. Only 67.5% of items are nearly all-natural (95%+ natural fibre), so check the composition before assuming a piece is pure cotton.
Is Madewell 100% cotton?
Some pieces are. Of the 456 Madewell products we analyzed, 187 are 100% cotton (or near-pure, 95%+) — that's 41.0% of the catalog. The rest are blends.
How much polyester does Madewell use?
3.7% of Madewell products are polyester-heavy, meaning polyester makes up 50% or more of the garment. This is below average for fast fashion retailers.
Is Madewell mostly synthetic?
3.7% of Madewell products are polyester-heavy (50%+ polyester). Average natural fibre content is 86.9%, so the rest of the catalog is mostly natural-led.
Does Madewell use natural fabrics?
67.5% of Madewell products are nearly all-natural (95%+ natural fibre). A decent portion of their range avoids synthetic fibres entirely.
Is Madewell sustainable in terms of fabric?
Fabric composition is one factor in sustainability. With an average of 86.9% natural fibre, Madewell is better than many competitors on this measure. Natural fibres generally biodegrade and shed fewer microplastics than synthetics.
