Far Infrared Rays (FIR) Technology: This support is crafted from high-performance neoprene laminated with a tourmaline coating. It emits far infrared rays with wavelengths of 4-14 microns, which are known to penetrate deeply into the tissues. This may enhance blood circulation and relieve joint discomfort. Negative Ion Generation: The tourmaline material not only emits FIR but also generates negative ions, which can help activate cells and promote a sense of wellness. Adjustable Universal Size Design: The neck support features an adjustable design, ensuring an anatomical and optimal fit for various neck sizes. This customization allows users to find their most comfortable level of support.
