AVID TECHNOLOGY PROGRESSIVE EPS MAXIMUM VENTILATION WITH HIGH PROTECTION A MIX OF ACTUAL AND VIRTUALLY DIFFERENT DENSITIES EFFECTIVELY MANAGES DIFFERENT KINDS OF IMPACTS Low Density Foam High Density Foam 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. 1 Low Density Foam: Optimum absorption at medium impact energy, may compress completely in high energy impacts. 2 High Density Foam: Imcomplete compression at low impact energy, optimum absorption at high impact energy Ventilation channels: virtually decrease density 1 & 2 Actual densities
