Kask Protone WG11 helmet, passes the severe WG11 test, the most updated international protocol to measure and apply the highest safety standards. This focuses on protection from rotational impact forces, measuring rotational kinematics from both oblique and normal impacts. Weighing just 230 grams, Protone features lower aerodynamic drag and faster heat dissipation coefficients than other ventilated helmets. The different ventilation holes and the thick padding material make the dissipation of heat and humidity very fast, improving comfort and performance without neglecting safety: the upper area is reinforced with an internal plastic substructure that increases the impact protection.
