Tencel is a fiber made from eucalyptus tree fibres.
Tencel feels fantastic. It is not sticky because it wicks away moisture easily and therefore feels cool. Tencel is as soft as silk and just as strong as polyester.
A nice property of Tencel is that moisture is absorbed so well in the fiber that bacteria do not feel at home in Tencel. That makes it very suitable for fabrics that you wear close to your skin.
You can wash and dry Tencel in the same way as cotton.
