A very satisfactory purchase

By Bob

Comments about AGV K-4 EVO Diapason Helmet:

This helmet has proven very satisfactory. The continuous rain on California's north coast has limited my riding time with the helmet, but: The sizing chart was correct and the helmet is the right shape for my head, so it is reassuringly snug but easy to put on and take off; it is much quieter than my other helmet and has a good range of vision; the visor and vents are easy to manage with gloves on; and the finish is quite good--a quality appearance. My only difficulty so far is that I haven't quite mastered the D ring closure, which is a little awkward. Overall, however, I am very satisfied with this purchase.
