Our Technology

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.
