What fabric are Mineral Undies made of?Updated a day ago

Our lining fabric is a unique blend of TENCEL™ Lyocell and smartcel™ sensitive with natural mineral, zinc oxide. 

TENCEL™ Lyocell fibers are biodegradable, come from Eucalyptus trees, and are produced in a sustainable closed-loop process with a 99.5% solvent recovery rate. Our special blend has a small amount of pharmaceutical grade zinc oxide permanently embedded into the fibers. TENCEL™ Lyocell fibers are derived from sustainably managed forests. 

TENCEL™ Modal x Micro fibers are mainly manufactured from the renewable raw material beech wood, sourced from sustainable forests in Austria and neighboring countries. In addition, smartcel™ sensitive is made from FSC certified wood.
