natural fiber wool sweaters

Acrylic is a plastic fiber. It traps heat, pills quickly, and sheds microplastics in the wash, and it doesn't breathe the way a natural fiber does. Wool, cashmere, and alpaca insulate while still letting the body breathe, which is why they wear so differently over time.

Wool is a natural animal fiber, free of the plastics in acrylic and polyester knits. It insulates, breathes, and resists odor without chemical treatments. Toxome scores each sweater by its fiber content so you can tell natural wool from a synthetic blend.

Fiber content is what touches the skin. Toxome reads each garment's composition and rates it, so the score reflects what the clothing is made of, not a brand's marketing.
