Very lightweight and comfortable, the Bollé ADAPT MIPS L (59-62 CM) cycling helmet is equipped with the MIPS technology. In case of a fall, the MIPS liner inside the helmet allows for a slight motion against the shell of the helmet to absorb rotational energy, The result is a significant reduction in these forces that would be transmitted to the brain. The helmet with AVID liner technology uses a combination of different EPS densities and optimized ventilation channels in the upper part of the helmet. The result is a lighter and better ventilated helmet with progressive shock absorption. You can easily adjust the size using a system integrated directly into the MIPS around the circumference of the head with an option for vertical adjustment. Thirteen air vents ensure perfect air circulation, reducing the possibility of your head sweating inside the helmet.
