This is a flow cap purchased from Karrimor. The shape is like a typical jet cap, but the sides are mesh, providing excellent breathability. I've used it several times, but it's not noticeably dirty and can be used for a wide range of activities, from everyday wear to mountain climbing. The color is black. A cap with excellent breathability that protects your head from strong sunlight and heat. It takes in air from the mesh on the sides of the body and expels heat from the head. The main body material is water-repellent, and the sweatband around the head is treated with antibacterial and deodorizing properties to prevent the growth of odor-causing bacteria. The soft brim material is easy to fold and doesn't wrinkle, making it suitable for storage in pockets, etc.
