With the lowest drag of any road helmet on the market, the Giro Air Attack Shield helmet introduces a new style to the peloton, challenging the competition with the perfect blend of aerodynamics and ventilation. Streamlined shell creates 12% less air resistance than the Aeon and 28% more cooling power than the Selector, thanks to the new Roc Loc Air fit system. Lightweight, aerodynamic-efficient design moves through the air with less resistance, giving you a boost of free speed. Revolutionary ventilation system with strategically placed vents and internal channels produce more energy for generating power, enhancing your overall efficiency. New Roc Loc Air fit system suspends the helmet just slightly off the top of your head, allowing air to pass freely in between the EPS and your head, for better fit, comfort and cooling. Magnetic eye shield provides wraparound eye protection that's easy to remove during pre-race or warm-up. The choice of sprinters, break-away specialists, criterium and cyclocross racers, track athletes and triathletes, the Giro Air Attack Shield sets the new standard in helmet design and performance.
