The MT500’s ventilation is awesome. Large vents and a top air intake control air circulation. Due to the arrangement of the tubular Koroyd® inserts, the airflow is optimized. Riding uphill, I forgot about the helmet very quickly. It’s “disappearance” was a good sign though, as it meant that the airflow was working well and the fit was good. The quick-drying, well-placed anti-bacterial padding also played its part here. I noticed no pressure points, even after hours of riding.
