Cervical retractor features an innovative front chin support. The three-zone airbag structure creates a snug fit to boost wearing comfort. It delivers 360° circumferential support, closely conforming to your neck and effectively dispersing cervical pressure to help improve forward head posture. Made of high-elastic material that resists deformation after repeated use, it supports rapid inflation for effortless operation. With a scientific high-front and low-back design, it fits the neck’s physiological curve and offers stable support on the clavicle and shoulders to prevent slipping. Its unique upper-small and lower-large structure avoids squeezing your face.
