Hey alan, this is the helmet i wear, it is very nice, I am like Sarris I feel like a full-face inhibits MY vision to the point of being dangerous, so I got this helmet. I realize that it is not quite as protective as a Full-face but I weighed the option of not being able to see and giving up a little bit of safety and took the latter route.
I used to wear a Beanie Style Helmet (AKA the Brain Bucket), but I have at least partially turned over a new safer leaf, Plus like Sarris said, the weather is rough on you in a Half Helmet, I even like the 3/4 helmet with a tinted face shield in the summer over the Beanie style, It is actually COOLER believe it or not.
