To protect themselves from the sun when they are attending to outdoor activity, soldiers and police officers are often seen wearing a cap, but like many other accessories that belong to their uniforms, there are some specifications to manufacture them.

The caps must be made with polyethylene and lightweight as they are worn in the head, also they cannot be hard. But the army textile companies have to make sure that they are not going to break, crack, or twist, as they have to keep their form in whatever situation.

The same goes for the hat visor, the top layer must be denominated in bright artificial leather material while its surface must be coated with polyvinyl chloride, the middle layer must be made of plastic and the thickness should be between 1.5 – 2 mm. The bottom layer should be done with matte faux leather material.
