Lightweight, safe and comfortable, these are the greatest advantages of helmets constructed with DOUBLE IN-MOLD technology, and this is exactly what the Companion is! The RTS system allows the size of the helmet to be adjusted around the entire circumference. The helmet has an effective thermoregulation system. Thanks to the ventilation channels between the helmet shell and the interior, which ensures a constant supply of fresh air and wicks away moisture, the interior is also made of anti-allergenic materials. The ventilation channel system is compatible with Marker's goggle ventilation system, always guaranteeing good clarity and rapid evaporation of the lens. Designed for a high level of safety, quick and easy handling and comfort in all conditions throughout the day. Helmet Marker Companion 143213-2
