Lightweight and ventilated, but undeniably urban. The REACT MIPSA(R) is developed to combine the performance of a road cycling helmet with a style inspired by the streets. Made with a dual shell construction, equipped with MIPSA(R) and Avid Progressive EPS, the REACT MIPSA(R) will protect you at all times. Its 13 vents along with the CoolmaxA(R) lining that drains moisture away will make you feel cool and ventilated in any conditions. Our new stylish urban helmet has a removable cap with reflective lining in case you are out at night. Ride in style with our new REACT MIPSA(R) helmet.HIGHLIGHTSAVID Progressive EPS13 ventsRemovable cap with reflective lineClick-To-Fit(TM) SystemMIPSA(R)Thin straps with 2 reflectives linesNon-slip, non-twist strap adjustorsDual shell constructionCoolmax liningFIT GUIDEMIPS TECHNOLOGYMULTI-DIRECTIONAL IMPACT PROTECTION SYSTEMMIPS ADDS MORE PROTECTION AGAINST ROTATIONAL MOTIONMIPS is a revolutionary technology that lets the helmet slide relative to the head, adding more protection against rotational motion to the brain caused by angled impacts. Because keeping you safe in every condition is our priority, the TRACKDOWN helmet is the first Bolle helmet equipped with MIPS technology.MIPS ENABLES A RELATIVE MOVEMENT BETWEEN THE HELMET AND THE HEAD IN ANY DIRECTION.= THE MORE RED THE MORE STRAINTHIS SIMULATION ILLUSTRATES STRAIN IN THE BRAIN FROM A SIMILAR ANGLED IMPACT WHEN THE USER IS WEARING A HELMET WITHOUT MIPS AND A HELMET WITH MIPS.AVID TECHNOLOGYPROGRESSIVE EPSMAXIMUM VENTILATION WITH HIGH PROTECTION A MIX OF ACTUAL AND VIRTUALLY DIFFERENT DENSITIES EFFECTIVELY MANAGES DIFFERENT KINDS OF IMPACTS 1 Low Density Foam: Optimum absorption at medium impact energy, may compress completely in high energy impacts. High Density Foam: Incomplete compression at low impact energy, optimum absorption at high impact energy Low Density FoamHigh Density FoamTo 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. Bolle 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*.
