AGV K4 EVO Diapason Helmet 4 5 1 1
Good Helmet could be better Took a chance with this helmet even though it didn't have any reviews but it turned out as a good purchase... However I was a little disappointed with the ventilation on the helmet. i bought the helmet in march when it was 40 out kept my head nice and warm! I didnt get to wear it in the heat until June where i found out about the vents. Overall it is a good helmet with good vision, good design, and light weight. its not snell approved which is disappointing for the price however im still happy with it! June 19, 2014
