<p><b>Sweat Smart Waist Trimmer does provide back support but is not intended for this use.</b> <br><p> The Sweat Smart Waist Trimmer is not a corset nor does it function like a corset. </p><p> Please do not wear over any open wounds, or if you're susceptible to dermatitis or allergic to Neoprene. </p><p> Do not wear for more than 2 hours as Neoprene is designed to be worn for only short periods of time. </p><p> Do not wear while sleeping. If you develop a rash discontinue use immediately. </p><p> New Neoprene often has something similar to a "wetsuit smell". </p><p> Don't worry, this will dissipate over a short time by washing and normal exposure to air.</p>
