The helmet is specifically designed for cycling, roller skating, scooters, and skateboarding. It is not intended for use in other sports or for riding motorized vehicles. It is constructed to absorb impacts. It is designed for use with: bicycles, scooters, roller skates, and skateboards. Its advantages include: lightweight, fixation system, maximum protection, optimal ventilation, In-Mold technology, removable visor, head circumference adjuster, 21 ventilation holes, thermopressed soft liner with insect mesh, weight of 260±10g, black-red matte color, size M (54-58 cm). The IN MOLD technology is the most advanced manufacturing method that achieves the highest protective properties with the lowest possible weight. The helmet's strong base is made of high-quality polystyrene using thermal and compression molding. The helmet improves shock absorption through better distribution of impact force. When manufacturing the Grey's helmet, great attention is paid to the maximum number of vents and, above all, to the ideal airflow inside the helmet.
