Hi guys. I have a flip front helmet that is too big to go into my box. I normally carry this into work but with the weather looking a tad better I am using my wheels to get out to more places and am going to need some way to secure my helmet. I have seen some types of special locks for helmets and jackets which look ok. I get that these are more like deterrents than preventative measures as a pair of pliers would render most of them pointless but I was wondering how many of you use helmet locks or something similar? Also have any of you had your stuff stolen / tampered with? I am not intending on leaving my jacket on the bike or anything, just the helmet. I have considered getting a bigger box but to be honest the one on it is pretty big already I just had the bad luck to buy a fat ass helmet before I got the bike, if I got any bigger box it would be a bit of an issue filtering and so on (or it feels that way for me at any rate). Cheers
