DERIT TECH was developed by a physical therapist who supports many famous athletes. Humans receive instructions from skin sensory receptors on whether to activate or relax muscles. DERIT TECH utilizes this skin sensory receptor with its "Low Muscle Pressure Theory®" and features unevenness on the fabric to move the muscles around the pelvis. This achieves the promotion of the pelvis to a correct neutral state without applying excessive fixation or compression.
