men's natural fiber tops

Usually cotton, polyester and rayon, in roughly equal parts. It is sold on softness and drape, and it is around half plastic. A tri-blend tee will score well below a 100% cotton one for that reason.

Linen is the most breathable common shirting fiber and it dries quickly, which is why it is the traditional hot-weather choice. It wrinkles, which is the trade-off, and it softens considerably after the first several washes.

Toxome reads each garment's fiber composition and scores it on what that fiber does to your body, not on a brand's sustainability marketing. A higher score means a cleaner fiber. Composition is taken from what the brand publishes, so the score reflects the label, not our opinion of it.
