Going through the how to quiet my boat reminded me that I need to buy new ear muffs for my soon to be born daughter for the san diego races. Anyone interested, My 5 year old has these as well as my nephew and they work well. Of course, the pink ones now being available is nice. These are a must for the fuelers and the alcy boats. I don't want them to have any excuse later not to answer when I am yelling at them. These are great and my daughter wears them whenever in the pits or at the races.
