Specifications Very Cool, Anti-Viral Treatment, Antibacterial & Deodorizing, Cool to the Touch, T-shaped Wire Material: Outer Fabric/100% Polyester, Lining/86% Nylon, 14% Polyurethane Origin: China Color: Ice Gray Size: M *This product is intended to suppress the spread of droplets and does not prevent viral infection (entry). *The anti-viral treatment has the effect of reducing the number of specific viruses on the fibers, but it is not intended for the treatment or prevention of disease. *Perceived temperature varies from person to person, and this product does not guarantee coolness. *To enhance the cool-to-the-touch effect, a smooth material with finely knitted fibers is used for the lining (skin side). Therefore, depending on the wearing situation, accidental snagging or repeated friction may cause fuzzing on the lining (skin side), but this does not affect the cool-to-the-touch effect during wear. *When wearing during sports, please refrain from use if it affects your health, such as difficulty breathing.
