Eco-leather chinstrap 3D DRY padding Coolmax fiber In moulding technology Octo fit Sanitized treated fabric Aero control With just 215g of weight, Protone has the lowest drag and the fastest heat dissipation coefficients compared to any other ventilated helmet. Thanks to several ventilation holes and a thick padding material, heat and moisture are dissipated very fast, improving comfort and performance without giving up on safety: the top area is reinforced with an internal plastic sub-structure that increases crash protection. The Protone weighs just 215g and uses a 3D Dry padding with a multi-layer open cell construction process to give a more comfortable ride. KASK has also continued to use its Multi In-Moulding Technology to create a polycarbonate cover for the top, base ring and the back of the helmet鈥檚 shell. This is joined to the inner polystyrene cap via KASK鈥檚 In-Moulding Technology to improve the shell鈥檚 shock absorption. Its strengthened frame further reduces the risk of a shock breaking the shell.
