Scott M.wrote a review of Giro Nine.10 Helmet on February 2, 2012
Really not impressed with this helmet right out of the box. So unimpressed I returned it without even trying it on. My old Giro Nine had a switch to operate the vents and nice think rubber plugs for the vents that were not controlled by the switch. This helmet has flimsy flaps that don't cover the vents sufficiently and no switch to control the ventilation. I'd be seriously worried about air leaks using this helmet.
