Our Technology


ThermaTech Vapor

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.


A key player in compression technology, SWEATtech combines layers of woven latex with curved metal rods. By creating excess warmth in these parts, your body produces more sweat and in turns allows you to get rid of excess water weight and toxins. The flexible SWEATtech rods compress and defines your shape over time, helping you achieve the real results you want.
