Nolan n-Com from J&M With the Elite (If you like Hi fidelity music) or standard (If you don't care) headset. Headset is preinstalled and the connector is built into the helmet. They sell the cord to go from that headset to a Harley, Goldwing, Beemer or J&M unit so one helmet will cover whatever bike you may be riding. My kid and I have the N-43 Trilogy, but I think its now the N44. 3/4 helmet but it has a quick change face shield to from visor to shield, and a snap in chin bar for cold weather or rain. Inner fighter pilot style flip up shade visor and the shield has the pinlock second shield that prevents ALL fog. Seriously. Huff and puff and it still won't fog.
The elite headset is as good as I've heard in a headset for audio fidelity. For just CB I stick with the cheaper one. The prices ain't cheap, but I've had very good luck with J&M products. But I will say I know some people have felt they're not durable. Not my experience, but I wanted to be fair.
