I bought an open-face helmet in preference to my existing full-face helmet as I'm a glasses wear and have problems with them misting up, especially in the winter. So I chose this helmet, mainly due to it's price and other reviews.
I found it quite comfortable but very noisy at speeds in excess of 55 mph. I will wear this helmet for local trips but will revert back to my full-face for longer journeys, purely due to the noise factor. However, the glasses misting problem is no longer an issue with the RS-16, once on the move.
Good value but shame about the noise insulation quality.
