Steve E.wrote a review of Kask Valegro Helmet on May 7, 2018
Out of the box, this helmet is light. Substantially lighter than my previous Bell Zephyr. I've already used it on a couple 85 degree + rides, and air flow is excellent. The helmet has a nice aero profile, with a trim back end. But the real aero benefit is not obvious until you actually ride with the helmet. Their is very little material (not even padding) at the front center (ie. between your eyebrows, center of forehead). This allows a better flat back position, as the brim of the helmet doesn't interfere with vision. The front corners of the helmet are built up for protection, so you're covered in the event of a crash. The lack of padding above the eyebrow also serves another feature: no sweat dripping into your eyes. The fit adjustment works fine. As for fit, the helmet is typical kask: rounder fit. I have a more oval shaped head, 59cm. I went with a large, and there is a bit of room on the sides. However, the fit is secure. The valegro also has a smaller profile than the kask protone. I would highly recommend the Valegro.
