Wall Rider: a good reason to start using a helmet

Some years ago, nobody wore a helmet on ski slopes but now people start using them and child cycling is going in the same direction. As loose rock is one of the biggest risks for rock climbers, it is strange that helmets have not gained popularity, at least for kids. Probably, this has something to do with the previous climbing helmets, which were heavy with no ventilation and goofy looks. Mammut's Wall Rider changes that and will probably have some good impact on climbers. It is made of expanded polypropylene foam, which gives better protection even if it is lighter in comparison to other foams. It is also equipped with numerous generous ventilation openings. Kind of a modern look as well. What do you think?
