Can anyone suggest a backpack thats big enough to fit a motorcycle crash helmet in?
I’ve got one made by Diesel. It’s just big enough to fit my helmet and my bike jacket (if I scrunch it up small) and it’s got a couple of big pockets for my phone etc. There’s loads of them about. Have a look around the outdoor shops and try a few for size. Nobody leaves their helmet locked to the helmet lock on their bike anymore. Some little scrote will just come along and cut the strap and have it away with your helmet and they’re not cheap. The net thingies are good but not secure. You could probably fit a top box or rigid panniers but they’ll probably cost more than your bloody bike is worth.
