but you must have luck that shoei Bangkok anwer your email
I am waiting more as 1 Year now
Like so many companies in Thailand, not all will answer emails... It's always best to visit the shop of call them... and if you cannot explain over the phone which helmet you want you can send an email... and call them if they have received the email...
Did you ever consider buying a modular helmet instead of the open face? Regardless, of the brand (and I bet you can find alternatives for Shoei within the same quality and price) I really recommend that you should consider keeping the safety/practical balance. With a modular helmet you can combine both the full-face and open-face features (more or less). I came across this article two-wheelers.com/full-face-helmets-open-face-helmets-half-helmets-modular-helmets/ and I found it very beneficial when it comes to explaining the different helmet categories.
