Super-ventilated, Easy riding. The Met Strale utilizes the Venturi Effect via an air channeling system that pulls in cool air and pushes heat out. Feather-light, wearing the Strale is unobtrusive, as any top range all-around helmet should be. It\'s the answer Super light, super comfortable, super cooling helmet. Available in 2 sizes and 7 striking colors, Strale is the solution to providing an optimal riding experience. In the details The MET Strale\'s exceptional air channeling system design features a large central vent that takes in cool air, along with side channels, maximizing overall ventilation. Thanks to the Venturi effect, hot air exits through the back exhausting vents, pushing it away from the rider. All of this while maintaining impressive aerodynamics, on a road helmet offering great value for the money in an exceptionally safe and innovative design.
