At What Waist we use the most innovative performance fabrics in our products, so we can bring you the best workout experience possible. Discover our signature technologies that make us more than just another fitness brand and learn how our science-based waist bands really work.

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 define your shape over time, helping you to achieve the real results you want.

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

Polystretch™ contours your abdomen and delivers the ultimate hold that gives you your most flattering silhouette instantly. The breathable multilayer woven technology is soft on the skin and naturally cooling, perfect for everyday wear. The best part, it’s undetectable under clothes!
