Only tried on, never used. Never used it outside. It was just a decoration in the house without a box. NOMAD JETHELMET M. Made with Mchal Karrera as the image source. The shell is made of FRP, using glass cloth and 600-grit glass mat to give it thickness and strength. To create the atmosphere of the time, the paint is deliberately rough, and the texture of the glass mat is faintly visible. All leather parts use domestic cowhide. Basically, the Nomad M size can be worn without any problems by people with a head size of around 58-60cm. Please understand that this is a decorative helmet and purchase accordingly.
