Don't forget Specialized Helmets with ANGi crash detection system. If you ride alone or in areas with limited population. The helmet tracks your location and notifies your contacts should a crash be detected. It is another layer of protection, I know someone had a bad crash on a trail and was severely concussed along with other injuries. Could not operate phone nor verbalize location post-crash, had to rely on someone who came down the trail an unknown period of time later. That sold the concept for me.
