What is the lining fabric made of? 

What fabrics are Huha Undies made of? We use  TENCEL™ Modal x Micro in our outer fabric, a super buttery soft cellulose fabric that's breathable and sustainable. Our lining fabric is a blend of TENCEL™ Lyocell which comes from Eucalyptus trees. It is also produced in a sustainable closed-loop process with a 99.5% solvent recovery rate. Lyocell is completely biodegradable. Our special blend lining fabric is further protected with pharmaceutical grade zinc oxide permanently embedded into the fibers.
