THOM BROWNE Two-color Four-strip Stripes Sunscreen ClothingIt is made of high-density polyester fabric, using FDY fully stretched polyester filament for high-density plain weave to form fine grid-like tear-resistant texture. The base fabric undergoes multiple post-treatments such as shaping, matte finishing, and micro-hole rolling polishing; the yarn is high-twist and shaped, with a stiff and soft fabric, a tight weave, and reserved ventilation gaps. The fabric is lightweight and foldable for easy storage. The microscopic grid texture on the fabric combined with the four-strip netting on the sleeves achieves two-way ventilation, preventing sweat from sticking to the skin. The high-density structure can also physically block ultraviolet rays, providing lightweight and breathable sun protection for daily commuting and outdoor activities.
