I had to send my aria viper back as the air vents at the front broke off in my hand and there was other parts off the helmet coming loose
top air vents and the side slat that the visor slots into was also fucked ! all this on a helmet a couple of months old!
I always washed it with warm water and the old warm wet kitchen towel on the visor to help remove bugs.
when i got it back it came back with a report saying that heavy chemical based cleaner had been the cause of the parts braking.
The only time it was ever cleaned with anything other than warm water was when i was out for a ride , usually at bike stops when there is a tub with a sponge and visor wash in it , so beware you never no what the fuck is in there , since then i have never used them but always see loads of bikers hapily washing the bugs of their visors and helmets.
There was also a warning of using a well known brand on the helmet and also one of the bike mags had an article on the brand doing damage to helmets , which was Auto Glym helmet care !
I also found that aria helmets seem to chip fairly easy well the two i have had certainly did . ( could just be unlucky i guess )
