"I have not used them yet, but they look to be very good quality. Some others in my running group have used them and recommended them to me, so I decided to give them a try. Running Nashville half marathon in a week and looking forward to putting them to the test. Running gear can be expensive and I would like not to put holes in the shirts/shorts when racing, so these should be perfect. I uploaded a person picture of my wife and I for one set of the bibboards and it turned out great. Personalizing them with a picture was extremely easy and the cost difference was not much more."
