Well I got one. It's the most comfortable helmet I've ever worn. It fits my head perfectly. It is fiberglass lined with cork and a thin padded liner around the circumference. The leather neck curtain is SOOO comfy and yes it is loud, but the roar at 50 is not much louder than the roar at 20, and unless I'm going on a long trip, I usually skip the pads or earplugs.
I got the "Aviator" type goggles that fit over glasses and they work great. I also got the leather face shield which REALLY helps with wind plus it looks bad ass. Does it provide the protection of a full or 3/4 face? No, but I'll bet it provides nearly the same protection of other half-helmets.
The only downside is the lack of visor makes riding into the sun a pisser. But that's a tradeoff I'm willing to make.
It is the most awesome helmet ever. The styling and look and fit and feel is perfect to me. I should have bought one a while ago.
I got the John Cooper "Racing Series" helmet. It looks like Blinky from Pac-Man is eating my head and when I stop and put up the goggles, it looks like the helmet is wearing the goggles. Everyone I see loves it and thinks it fits my personality perfectly.
