H&M: June 2026

Based on our analysis of 513 H&M products, the average garment is 55.5% natural fibre. The most common single fibre is Cotton (in 50.7% of products). The remaining material is typically synthetic — polyester, polyamide, or acrylic.

Sometimes — cotton appears in 50.7% of the 513 H&M products we analyzed, but it's usually blended with synthetics. Only 34.9% of items are nearly all-natural (95%+ natural fibre), so check the composition before assuming a piece is pure cotton.

Effectively no. We didn't find any H&M products that are 100% cotton (or near-pure, 95%+) in our database. Cotton at H&M is almost always blended with elastane, polyester, or other fibres.
