Agree with looking for the CPSC approval. I do not particularly agree with the statement "Forget buying online, there is a lot of junk out there." Yes there is some junk out there, but there are reputable bicycle merchants as well. Having said that, I believe supporting local bike shops is the right thing to do and it will give you the opportunity to try helmets on to find what fits and suits you best. Also, you should know when comparing helmets you will encounter a range in price, but a higher priced helmet does not necessarily offer greater protection than a less expensive one. The difference is the more expensive helmets offer the same level of protection, but typically with less weight, perhaps more ventilation and retention systems. These may be of interest to you, but not necessary for a basic quality helmet.Ensure it is CPSC approved and fits comfortably, a good cycle shop is invaluable. Forget buying online, there is a lot of junk out there.
