Hi, Next May I will be visiting my son in USA and I would like to buy a new helmet, avoiding the extortionate prices charged here in Brazil ... Currently I have one for everyday use (Xpeed XFC3000) but I hate its high level of noise and poor ventilation. I know I should wear ear protection, but can not get used to them. I'm considering one of the options below: a) Shoei Neotec - ~ 595 usd; b) Nolan N104 - ~ 360 usd; c) Schuberth C3 - ~ 650 usd. I know that the experience with helmets relies heavily on combination rider/motorcycle/gear, beyond other factors, but I would be very happy to hear from you about your experience on them or any other good options.
