What the brand names mean

Trademarks on a label describe the fiber, not your exposure. Here is what each one is and what it does not cover. None of it moves the score.

TENCEL™ Lyocellscored as lyocell

The spelled-out TENCEL name guarantees the closed-loop process: the solvent is non-toxic and over 99 percent of it is captured and reused instead of discharged. It is the cleanest regenerated fiber we score.

It covers the fiber, not the finished piece. Dyes and wrinkle-proof coatings go on after spinning, and that is where formaldehyde shows up. Look for OEKO-TEX on the garment too.

Backed by something

what it is made of

The Active Ultralite Short Sleeve is 53% merino wool, 47% lyocell. Merino wool is fine enough to feel soft, regulates temperature without synthetic finishes. Lyocell is a clean fiber regenerated from wood in a closed loop that reuses its solvent. That composition is what Toxome scores, and it earns 89 out of 100 on the fiber scale, where 100 is cleanest.

FAQ

What is the Active Ultralite Short Sleeve made of?

It is 53% merino wool, blended with 47% lyocell.

Is merino wool safe to wear?

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.

How does Toxome score clothing?

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.
