So did anyone know that these types of systems are available?
They are located in North Vancouver. I was able to try a few vests on and found that they are all a comfortable fit. I couldn't even feel that it was on. The only difference I found is each model's air bags is positioned a little different in the vest.
I have one now and might be crash testing one sometime through the WMRC race season. It might be the best investment I ever made.
