Regarding your question- we didn't have too much trouble finding a good fit, actually. Tried several sizes of this helmet at a chain store (dicks sporting goods, I think), after finding the right size I ended up ordering one off the internet as the store didnt have many styles in stock. We have gotten a new replacement about every 2-3 seasons. The first season he used resort rental helmets, although I am unsure of them- its hard to tell how old they are or if they've ever been on someone who smacked their head and didn't get replaced as they should have.
