Amid frequent heatwave alerts, sun-protective clothing has become essential. A leading Chinese sportswear brand launched next-gen "Air Sunshirts" featuring polysilazane (PSZ) nano-coating. At just 0.1mm thick, it achieves UPF50+ UV blockage while boosting breathability by 40% vs. traditional coatings. Polysilazane’s heat resistance maintains sun-blocking efficacy after 50+ washes, and its inorganic composition eliminates chemical allergen risks. Users report: "Feels like wearing a breeze—no back sweat during hikes." Experts note this innovation could replace eco-unfriendly fluorinated waterproofers in outdoor gear.
