Frequently asked questions.

What is Massimo Dutti clothing made of?

Based on our analysis of 2,235 Massimo Dutti products, the average garment is 76.7% natural fibre. The most common single fibre is Cotton (in 35.3% of products). The remaining material is typically synthetic — polyester, polyamide, or acrylic.

Is Massimo Dutti cotton?

Sometimes — cotton appears in 35.3% of the 2,235 Massimo Dutti products we analyzed, but it's usually blended with synthetics. Only 49.4% of items are nearly all-natural (95%+ natural fibre), so check the composition before assuming a piece is pure cotton.

Is Massimo Dutti 100% cotton?

Some pieces are. Of the 2,235 Massimo Dutti products we analyzed, 361 are 100% cotton (or near-pure, 95%+) — that's 16.2% of the catalog. The rest are blends.

How much polyester does Massimo Dutti use?

1.5% of Massimo Dutti products are polyester-heavy, meaning polyester makes up 50% or more of the garment. This is below average for fast fashion retailers.

Is Massimo Dutti mostly synthetic?

1.5% of Massimo Dutti products are polyester-heavy (50%+ polyester). Average natural fibre content is 76.7%, so the rest of the catalog is mostly natural-led.

Does Massimo Dutti use natural fabrics?

49.4% of Massimo Dutti products are nearly all-natural (95%+ natural fibre). A decent portion of their range avoids synthetic fibres entirely.

Is Massimo Dutti sustainable in terms of fabric?

Fabric composition is one factor in sustainability. With an average of 76.7% natural fibre, Massimo Dutti is better than many competitors on this measure. Natural fibres generally biodegrade and shed fewer microplastics than synthetics.

Methodology: We analyzed 2,235 Massimo Duttiproduct pages, extracting the fabric composition listed by the retailer. Products are categorized by name keywords. Natural fibre percentage is the sum of all natural fibres (cotton, linen, silk, wool, viscose, lyocell, etc.) in each product's composition. Data is refreshed monthly.
