Achieve perfect alignment when you wear the Posture Reminder T-Shirt. Featuring Posture Alignment Technology, this shirt reminds you to keep sitting up straight. The shirt features a smart back panel that will guide the wearer to keep their shoulder blades back and together. As a result, your spine is aligned and you instantly activate muscles and engage your core. Over time, you’ll gain muscle memory and begin to sit with better posture consistently. Even with this impressive technology, the Posture Reminder T-Shirt remains loose and comfortable for all-day wear. The nylon and Spandex blend also offers the perfect shape with less bulk and total softness. Coming in black, the shirt comes in four sizes for men and four for women.
