I hammered it into my kids to always were a helmet so much that they enjoy wearing their helmets so much that they'll wear then for hours inside the house. My son at four is a die hard helmet rocker as sometime I have to tell him to take it off at the table eatting meals. I catch him quite a bit fully decked out in his race duds. These are pretty funny to say the least...
