95% merino wool, 5% cashmere
The Herdsman Crew is 95% merino wool, 5% cashmere. Merino wool is fine enough to feel soft, regulates temperature without synthetic finishes. Cashmere is soft goat down that insulates without the plastic of acrylic knits. That composition is what Toxome scores, and it earns 90 out of 100 on the fiber scale, where 100 is cleanest.

It is 95% merino wool, blended with 5% cashmere.
Merino wool is fine enough to feel soft, regulates temperature without synthetic finishes. Toxome rates every fiber on what it does to the body of the person wearing it, and publishes the reasoning rather than a badge. The score covers the fiber, not the dyes and finishes a mill adds later.
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 rather than our opinion of it.
