You should never buy a helmet without trying on different sizes and brands.  The shape of your head and face make a difference in how a helmet fits and feels so you must test fit.

Answer 4

best thing to do is go into a motorcycle shop and try them on the helmet should fit snug on your head ,if there is a cyclegear store in your area go in and see what they have, It is  the only place I know of that lets you try it on ,buy it and ride with it and if your not happy with the helmet for any reason with in 7 days of buying it you can take it back and exchange it for another one they have a website as well.
