The Metronaut is a good compromise for people like me who are reluctant to wear a helmet, because of the optics. The cover is secured with Velcro straps on a normal helmet, the wearing comfort is acceptable, the setting by turning the knob back simple. The helmet is larger than I had expected, on the head, he is reminiscent of a jockey helmet. The shield forward, I find very handy when the sun and rain. The helmet is relatively light, the coating protects against cooler weather from the wind, but is also at temperatures up to +20 degrees still ventilated sufficiently.
