Cellulosic fiber supplier Lenzing is presenting a new fiber with solar protection. Tencel SUN fiber is effective due to permanent pigment integration. The latter comes from minerals and provides long-term protection from solar radiation. Even after several washes, Tencel SUN maintains its effectiveness. Tests show that a sunscreen level of up to 110 SPF can be reached.
Tencel Sun is made from the natural raw material wood and is, therefore, 100% biodegradable.
