This cervical air traction collar adopts a scientific high-front and low-back design. It conforms to the physiological curve of the neck to disperse pressure evenly, provides stable support against the clavicle and shoulders, and stays firmly fixed without slipping. Featuring an upper-small and lower-large structure, it won’t squeeze your face. The zoned support design lifts your chin effectively to improve forward head posture. Built with an inner circular shape and compact structure, it delivers snug and comfortable wearing experience.
