Our umbrellas are generally made of polyester, PG fabric, nylon, transparent plastic, etc., used for shading and blocking rain. In the summer sun protection product market, UV resistant sun umbrellas are highly favored. Umbrellas play an important role in sun protection. Firstly, a sun umbrella can not only block sunlight and reduce the damage of ultraviolet rays to the skin, but also block rainwater on rainy days, preventing clothing and shoes from getting wet. Secondly, outdoor leisure umbrellas are usually placed in public places such as parks, communities, and squares, providing people with shading and rain protection functions, making outdoor leisure activities more comfortable. These features not only protect people's skin from sunlight damage, but also improve the comfort of outdoor activities.
