I signed up for my first autocross on may 7
I was planning on borrowing the helmet on-site ... but the registration page says helmets are all sold out
So I may need to buy a helmet before this coming sat

Any suggestions for a local store around LA? So I can go and try on helmets before buying
Or are there some brands/models that are the go-to ones?
I am probably going to get a closed face because I do want to move onto track events as well and don't want to buy another helmet for it
