EquiFit® ShouldersBack™ Lite offers the same upper back support as ShouldersBack, in a sheer fabric for warm seasons and climates. Developed by a leading orthopedic team to help rider’s improve posture, ShouldersBack™ is also worn by professional athletes, dancers, chiropractors, dental hygienists, actors and models. With consistent use ShouldersBack helps retrain your mind and muscles to stay in a correct, upright position. ShouldersBack™ is comfortable, breathable and does not restrict nor hinder your movement. Because ShouldersBack™ does alter your positioning, we recommend beginning slowly and listening to your body. Slip it on for just one hour a day and, if it feels good to you, gradually increase the time to your comfort level. ShouldersBack is great for both men and women.
