Independent testing has confirmed that almost all helmets do very well in a crash. More expensive helmets fared not better than cheap ones, but they did make their riders look a lot cooler while getting hit by a car. Your head is an investment that is worth putting some money into and looking decent can be important to some people. Do not buy a helmet based on price point but on fit. If an expensive helmet looks cool and cost a lot but fits poorly, it can fly off your head in an accident and generally not protect you nearly as well as a cheap good fitting helmet. Make sure you buy from a well know brand so that they meet all the crash standards!
