Mother Nature is our muse. Building on her handiwork, we’re finding new uses for materials that exist right in front of us. Like trees, rockstars of the forest.

Thanks to their fiber and a clean closed-loop process, we have a naturally-derived, renewable material that’s much easier on the environment than traditional fabrics. Did we mention it’s also comfortable, breathable, and silky-smooth?

Rooted in Sustainability

Our Tree fiber—TENCEL™ Lyocell—is mainly sourced from wood grown in South Africa. The cultivation relies on natural rainfall, which means there's no need for artificial irrigation and fertilizers. Compared to traditional materials, TENCEL™️ Lyocell uses 95% less water than conventional cotton and has a carbon footprint that is one-third lower than virgin nylon.
