A good product for a bicycle helmet. The really only downside was the hood: it is quickly dirty. Many children leave their helmet lying everywhere and remove the raincover not. Therefore now and wash with warm soapy water, so that the reflection characteristics come into play. In summer, is negligible, since one biases the hood only temporarily on the helmet - in winter it is but rather a permanent condition. And at night the dome is due to the wide visibility really good !!!
