ThermaTech™

Our signature silver lining is made from a unique metallic material that’s designed to trap your body heat, making you sweat and increasing the amount of fat cells you lose. ThermaTech™ Vapor is also antimicrobial, soft on skin and naturally cooling, so you never have to worry about feeling sticky and you can keep smelling fresh when you hit the gym. It never stops working and is totally exclusive to What Waist. You won’t find it anywhere else.
