It is time to get a helmet. I am very into comfort, air circulation and weight. I wear an extra large hat so I assume same goes for helmet. Someone told me there are helmets with blue tooth capability w/ speakers etc? This sounds very interesting to me. Will this add much to the overall weight? Anyway, I am looking for suggestions please. I am mainly a cruiser. I like steep black diamonds and groomed blue squares.....I am just looking to keep up wit the trends since I noticed everyone wears helmets now. Having the Bluetooth/speaker capability is not a must-have, but I want to explore both options. Thanks All!!!
