Cleanroom hoods and caps are work wear for covering your head and face, suitable for use in cleanrooms. Measures to combat static electricity and dust are taken, such as using conductive fibers and light deodorant fibers for the material, processed yarn, etc. In addition, breathable caps and hoods are commonplace. Hoods are available with integrated masks or with brims. The shape of the cap can be selected from shallow cover types or deep cover types. In addition, products with a net or products that fit when worn with a string or rubber will prevent the hair from falling, and wearing an inner net in a cap or hood also has a preventive effect. Since the compatible products differ depending on the class of the cleanroom, select the product according to the operating environment.
