non-toxic bras

A breathable natural fiber worn against the skin all day: organic cotton and hemp let heat and moisture escape, and silk regulates temperature without trapping it. All three beat polyester and nylon, which hold heat against warm skin. Every bra here is built on a natural fiber and scored by Toxome.

Polyester and nylon are plastic fibers that trap heat and moisture and don't breathe the way cotton does. Worn tight against warm, sensitive skin all day, a natural fiber like organic cotton, hemp, or silk is the cleaner choice.

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.
