TENCEL®: An Eco-Friendly Fiber

TENCEL® is one of the most environmentally friendly regenerated fibers. This natural fiber is extracted from eucalyptus wood pulp cellulose and is 100% biodegradable and organic.

The production of TENCEL® is revolutionary. It’s based on a solvent spinning process and nearly 100% of the solvent is recovered during the process, with the remainder of emissions being broken down in biological water treatment plants. The closed loop production process makes this fiber eco-friendly and economical. Plus, no harsh chemicals additives are used.

Did you know? It takes 100x more water to produce Cotton than TENCEL®.

Benefits of TENCEL® 

TENCEL® provides silky comfort and technical performance you can feel. Unique fibrils (or tiny hairs) make up the fiber. These help wick moisture at many points and disperse it throughout the fiber to evaporate quickly helping dry time and helps inhibit bacteria in the sock. The fibrils also give it excellent functional properties — it’s as strong as polyester, cool as linen, warm as wool and as absorbent as cotton. 

Moisture Management

TENCEL® deals with moisture like no other. The fiber absorbs moisture completely and naturally and then releases it to the outside. Submicroscopic channels between the individual fibrils regulate absorption and release of moisture. Thus, these tiny fibrils assure the optimum transportation of moisture. TENCEL® really stands out when compared with cotton. Compared to cotton, TENCEL® absorbs the moisture in a controlled and regular manner. With TENCEL® a 50 % improvement in moisture management was measured.

Softer than Silk

Since the textile has a smooth surface, the softness is appreciable and prevents irritations to the skin. Thus, TENCEL® promotes an optimal skin feeling thanks to the smooth fiber surface. Rough fiber surfaces can cause skin irritations. Compared to the fiber surfaces of cotton and wool, it is clear that TENCEL® is much smoother and softer on the skin.

Reduced Bacteria Growth

The growth of bacteria can be restricted completely naturally without chemical additives. A test demonstrates that the growth of bacteria on TENCEL® is greatly reduced. In synthetic fibers, on the other hand, the number of bacteria increases by up to 2000 times.


TENCEL® is also blended with another sustainable fiber, Merino wool.

Merino wool is a natural, renewable fiber that is gathered from sheep once a year and sheep produce a new fleece every year. The wool is then specially milled without harsh chemicals or extreme temperatures. It’s composed of a natural protein that is biodegradable, opposed to synthetic fibers that can be extremely slow to degrade.
Merino wool is the perfect fiber choice no matter the temperature. It thermoregulates, keeping you cool in the heat and warm in the cold. The soft fibers keep you itch-free while drawing moisture away from your skin.
Merino and TENCEL® blend together to increase performance factors.
