Everytime I go to buy one I just don't see one that I like. I grew up before helmets were introduced to cycling except for professionals of course. I do tend to like Bern helmets over others. It looks like it would protect the back of your head better if you fell backwards. Some bicycle helmets look as if they would simply be pushed forward and your head would still impact the ground due to the design. Here is a helmet I like.
