At The Filtery, we love natural and organic fabrics, as they tend to be generally better for human as well as environmental health. But not all synthetics are bad either!

We recently did a deep dive into rayon fabric and whether or not it’s toxic for the planet, garment workers, and/or consumers. (Spoiler: it’s not great.)

However, there are a few types of rayon that are much better than others… and TENCEL is one of those!

So today, we’ll talk briefly about why TENCEL is a fabric worth wearing and then we’ll give you what you came here for: our picks for the best brands making TENCEL underwear.

P.S. If you’re looking for other types of non-toxic and organic underwear, check out these related guides:

What is TENCEL?

TENCEL is a lyocell (rayon) fabric that’s made by a company called Lenzing. It’s a semi-synthetic fabric made out of wood pulp from FSC-certified eucalyptus trees. Unlike most other types of rayon, Lenzing’s TENCEL is manufactured using a closed-loop process, which means all of the chemicals used to produce it are kept from being dumped into the atmosphere or waterways. This, combined with the actual chemicals used, are what makes TENCEL a much safer, less toxic type of rayon fabric.

What Does TENCEL Feel Like?

TENCEL is actually an amazing fabric. It’s really soft, but it’s not thick like cotton or thin like silk. It’s somewhere in the middle.

One of the best parts about TENCEL is that it actually has temperature regulating properties. Even after you’ve been wearing TENCEL for a long period of time, it remains slightly cool to the touch.

This is why TENCEL bed sheets and blankets can be so great for those who tend to sleep hot! This is also why TENCEL can make a great choice for non-toxic underwear. If you’re in a hot environment, moving around a lot, or exercising, it can help to keep your private parts cool, minimizing sweat and moisture.
