The Fox Speedframe is the perfect helmet for trail riders, with its half-shell design. It provides good protection in the neck, without weighing too much, or being in the way. The 14 large ventilation holes keep the head cool. The visor can be adjusted up or down as needed. It can also be removed completely if desired. The buckle system in the neck ensures a good fit of the helmet and holds it firmly on the head. In addition, it also has MIPS which adds an extra layer of security.
