Kask engineers carefully shaped the profile of the Valegro's polycarbonate shell and verified the results in the wind tunnel, creating exceptional cooling performance and heat exchange, the perfect recipe for a helmet to keep your head cool on climbs in July. The Valegro offers its impressive cooling through 37 vents and the new breathable and quick-dry pads. This 5mm thick 3D DRY padding is anti-static and anti-odor and has a multi-layer open cell construction process so it wicks away sweat while remaining extremely comfortable. And because your perspiration evaporates quickly, less humidity is formed so the temperature remains more constant.
