Material Guides
Comprehensive sustainability profiles for every textile, scored 0–100
Looking for sustainable fabrics and textiles? Our material guides break down the environmental impact of every fiber — from organic cotton to recycled polyester — using the Fashion Sustainability Index (FSI). Each guide covers carbon footprint, water use, chemical impact, pollution, and biodegradability, so you can make informed choices about what goes in your wardrobe.
Use the filters below to explore by fiber type or score range, or sort by environmental performance to see which materials come out on top.
