What cotton is

Cotton is nearly pure cellulose straight from the boll. It contains no plastic, biodegrades completely, and its shed fibers are food for microbes rather than permanent pollution.

Its honest downsides are water and pesticides in conventional farming — organic and rain-fed cotton address much of that. The trap to watch is the blend: “cotton-rich” often means 60% cotton, 40% polyester, and stretchy “cotton” tees usually carry elastane.

How Plastfri scores it

Cotton scores 0/100. Blends score by their synthetic share — a 95/5 cotton-elastane tee shows 5/100, low but honestly not zero.

The same weight applies everywhere: a product's score is the percentage-weighted plastic share of its listed fiber composition, and every weight is public.
