It adopts a three-layer composite structure (polyester fiber core + polypropylene fiber layer + acrylic fiber layer), with the outer layer covered by flame-retardant fiber layer, high-molecular optical fiber layer and polyimide fiber layer, achieving flame-retardant anti-aging, anti-light aging and electromagnetic shielding functions. The surface adopts a combination of friction bumps and nano-breathable micro-pores to enhance wearing stability and improve breathability. The polytetrafluoroethylene strip design extends the service life. Ergonomic design By widening the flat hook and thickening the strap, the pressure on the neck is reduced. Combined with the 360° rotating hook head design, it can be inserted and unplugged smoothly and is less likely to scratch the clothes. The surface texture is clear, and there is no neck constricting sensation when worn for a long time. Moreover, there are a wide range of color options, suitable for various scenarios.
