Gettnig a Helmet in Hanoi?
 

Is there any chance at all. I'm backpacking in china and so am carrying my moto x knee/shins, some goggles and some gloves but i really want a helmet but can't warrant carrying one with me.

Will i be able to possibly pick one up in Hanoi or will i have to buy one in Hong Kong?

hallo and enjoy Vietnam..there are helmets everywhere for sale in the country and seemingly half the country on a wee 125cc without a helmet although they are mandatory and available for about 7 US dollars or 100,000 dong along the side of the road outside of every town and city inthe country, along with sunnys and BB caps and great fruit. Enjoy it...cops stop you then automatically pay em 50,000 or 3.50 US but they shouldn't stop you esp. if you're wearing the "rice cooker".

best of luck G
