Waist Trimmer. It’s durable, lightweight, and flexible allowing for a wide range of movements while providing therapeutic heat compression to the midsection and back. Made with extra-thick, latex-free Neoprene that may help the body sweat more during exercise. But don’t worry about the extra Sweat, the Trimmer’s grid inner lining will not only repel moisture absorption but also limit slipping and bunching during exercise. Includes Sweet Sweat sample gel packet and mesh bag to store or wash the waist trimmer.
