Marker M4 Ski and Snowboard Helmet is a lightweight in-molded helmet with a new adjustable Drawing Flow Control and Double Shell Technology.
With Marker's In-Molded Technology the external surface of the helmet is merged with the internal EPS shell by injecting the material into the heat-molded extra-thin polycarbonate external shell. This assures a perfect and consistent adhesion of the two materials, providing the helmet with unsurpassed strength and durability. In-Molded Technology also offers superior scratch protection, resisting damage for many years of hard use.
Double Shell Technology results in helmets with considerably less volume, especially in the back, which provides an incredibly close-fitting and encompassing helmet. This technology consists of an inner and outer cap which permits for a Drawing Flow Control ventilation current. This innovative air flow control system inside the helmet uses the hollow space between the two shells to provide the aeration and channel the air from front to back.
