From the manufacturer

Electric Plus - E-bike recommended. The ideal companion on all-mountain and trail rides, the Trail Evo provides all-round protection with patented in mould technology due to direct fusion of the helmet shell to the internal EPS (expanded polystyrene foam) material. The numerous ventilation openings have been strategically angled and positioned to offer superior air circulation and a continuous cooling system. Precision interlocking ErgoFit Ultra allows you to adjust the fitting ring both vertically and circumference-wise, guaranteeing a precise and comfortable fit for any head. With the quick release visor system, the visor can quickly detach in the event of a crash, preventing further damage or breakage both to the rider and visor.
