I am looking at a new helmet and not sure what I want so need some advice and suggestions...I have considered a half helmet but would also be interested in a 3/4 or open face... I want something I can use my Scala blue-tooth system with.. I would like something when nice can have face in wind but when bad weather won't freeze face or get pounded by rain... Would like something around the $100 mark.. can go a little higher but not looking for a $300 helmet...
