Function Analysis of Vintage Umbrellas.Chanel, based on SSV-olyester Fibre umbrella fabric and LRC coating, has improved the fabric density and upgraded the frame material to enhance sun protection and user experience. It effectively blocks 99% of direct ultraviolet rays on the umbrella surface. Additionally, with high-pressure, tightly woven fabric, the remaining 1% of UV rays are repeatedly absorbed within the gaps of the fabric, ultimately achieving 100% sun protection. Not to mention, the rain protection is also exceptional.
