I see that there has been some comment about wearing a light in weight chest protector if you are a tennis player. Rarely do you take a ball in the chest but it can happen looking for feed back and which one do you like thanks

I have a well tuned pacer. I hardly know I have it. I am 76 year old, hike and camp alone in the desert. I have more energy than I have had in a long time. The only problem is my wife wants to have a knob installed so she can turn the pacer down.
