My daughter and I are new riders. Not knowing any better, I purchased helmets for us that were in the $50-60 range- I think one is "TuffRider" and one is "Troxel." I didn't think anything of it until I saw a website that was selling helmets for close to $300! YIKES! Can you tell me if it is important to get these higher-end types of helmets or are the ones we have okay for now? Are the more expensive ones for showing? Of course, I want the safest helmets possible, but the large price tag blew me away. Thanks for any guidance here.
