Methodology in one paragraph
Fibr scrapes the public product catalogue of 55 fashion retailers monthly. For each of the 76,777products in this snapshot we parse the brand's own composition label into a per-fibre percentage. Natural fibres (cotton, wool, linen, silk, hemp, cashmere, etc.) count at weight 1.0; regenerated cellulose (viscose, modal, lyocell) at 0.5; petroleum-based fibres (polyester, polyamide, elastane, acrylic) at 0. A brand needs at least 30 in-scope products to appear in a ranking. No lab tests, no estimates, no proprietary scoring. Read the full methodology →
