My daughter bought an HJC helmet abt. 3 years ago. The visor has a small black latch to hold it closed. When she went to open the latch with a gloved hand, the latch fell off leaving a small crack in the visor. HJC sent her a replacement FoC. She was even more careful with this one, but it did the same thing. HJC don't want to know. Helmet City (West Bay) have given her a replacement at cost. The were unable to get one from HJC as they had run out, so they took one off a new helmet for her

and said that they had had a lot of similar cases (one chap was on his 7th visor!).
I doubt whether my daughter has worn her helmet more than 30-40 times in 3 years.
