It's heavy. To be fair, all the reviews before mentioned this, but I dismissed it as being insignificant - I've worn heavier helmets than what I have now (L Shoei Neotec) and have never had any issues before. But I quickly discovered it's not the weight, it's the balance. All that weight causes the whole helmet to dip to the front right. Of course the buckle on a helmet is meant to keep it from coming off of your head, it's not necessarily meant to cinch it down, so tightening that doesn't help. I found myself constantly adjusting my helmet, only to have it slide back down. It's subtle, but it's enough to notice. And of course as it slides over time, you're constantly adjusting the angle of the HUD.
