The Nolan N102 is nice. Way better than my HJC Symax. Plus it is DOT approved and approved by Eropean Standards which I am told is much harder to get than Snell. They put the button in the middle of the chin bar instead on both sides like the Xlite 1002 or the old N100. When you push the button it raises a small lever like thingy that you must also pull on in conjunction with the button to open it. This is supposed to be better and stronger to eliminate it from opening during a crash. Hope I never have to find out if it works or not. My most comfortable helmet is an Arai full face Quantum.
