The fabric, crafted from raw yarn with a biomimetic helical structure, features excellent breathable, moisture-wicking, and anti-UV properties. The helical fibers of the yarn are meticulously arranged in a specific direction for high loft, which, paired with aerodynamic 3D micro-grooves, greatly increases fiber surface area to enable efficient moisture absorption and evaporation for breathability. This also naturally forms a UV-blocking layer, achieving UPF100+ protection without chemical additives. The spandex-free fabric still boasts lasting elasticity, while resisting deformation and aging.
