MAXIMUM VENTILATION WITH HIGH PROTECTION
A MIX OF ACTUAL AND VIRTUALLY DIFFERENT DENSITIES EFFECTIVELY MANAGES DIFFERENT KINDS OF IMPACTS
To create helmets that perform against all types of impacts, the details are key. High-density EPS ensures that high energy impacts are effectively absorbed. Low-density EPS, however, provides superior performance against less severe impacts. Bollé helmets with AViD liner technology use a combination of different EPS densities and/ or optimization of the ventilation channels to virtually decrease the density in the upper area. The result is a lighter, better-ventilated helmet with progressive shock absorption that will absorb a wider range of impacts*. (Available on the Trackdown & Instinct.) *compared to a standard EPS liner with uniform thickness.
Low Density Foam: Optimum absorption at medium impact energy, may compress completely in high energy impacts.
High Density Foam: Imcomplete compression at low impact energy, optimum absorption at high impact energy
Ventilation channels: virtually decrease density
