I wear one but don't put a lot of stock in them. I need a new one, and my 7 year old twins ride and roller blade a lot too and could use more protective ones. Looking for opinions on the best type of helmet? I would like something that covers the back of the head more than a typical bike helmet. Is that more of a skateboard helmet, or maybe a downhill mnt. bike helmet? I don't have much clue without googling pictures.. Not sure if it's the shape of my sons head, but his helmet always rides to the back and leaves his forehead exposed with multiple normal bike helmets. And I know how to properly fit them. Thanks for advice and opinions.
