I just wanted to put something out there about 509. I have a close friend that owns a 509 helmet as do I. However he had some small issues with his helmet and called 509 for some help. Not only did 509 quickly work to resolve his issues when they could not fully correct the issue they bought him a brand new helmet. This company has some of the best customer service I have ever seen. 509 You have several customers for life. Keep up the good work and awesome products.
