First, apologies in advance, I am usually incapable of giving short answers so, here goes...I've got an N90 I really like. Here is what I've found - A pro and a con is the finish. They have a very scratch resistant finish - good. However, it is also brittle - bad. Not too long after purchasing, I was carrying it by the strap (as I had my older helmet) but, since it doesn't use D rings it slipped from my grasp. The short drop cracked/chipped that outer finish. The paint and shell were okay so, have kept using it. If I carry it by the strap now, I buckle it together first. Speaking of the strap, I really like the latch mechanism. I don't have to kick myself if I forget and put my gloves on first, as it is very easy to latch and unlatch even with winter gloves on, where I found D-rings very cumbersome unless I was not gloved. Compared to the HJC IS MAX BT I used previously, it is quieter; the chin bar is easier to latch in place and I prefer the double-latch mechanism for it; the sun visor is more effective and to me, easier to use; the face shield has a center tab to lift up so, it doesn't tend to bind when lifting it like the HJC did with its offset lift tab; it comes with a chin wind guard (appreciated in the winter) and; the Nolan has far less, if any leakage in the rain. The only other negative about the Nolan I can think of is that for some reason, the detentes that hold the face shield up at various positions aren't all the same, with the uppermost not being as solid. Not only is this visible by inspection (they are visible at the hinge mechanism) but, when riding with the face shield in the uppermost position at higher speeds or with extra backdraft from particular riding conditions, the shield tends to suddenly blow down. As I wear glasses and thus have eye protection, I prefer to ride with it up except in rainy or cold conditions. I may try to deepen those top detentes a little. Because of the black plastic trim piece along the lower edge, I had to cut a small hole in it to pass through the clamp mechanism of my Scala Rider communicator. Afterwards, I remembered I had a stick on pad that could have avoided that but, no big deal. All in all, like I said, I really like the helmet.
