Input:
We have purchased this helmet twice.  The first purchase was a good experience and the helmet worked and fit well.  Unfortunately, we lost the helmet.  The second time it was purchased it broke shortly after purchase but just past the window to return it.  The part that adjusts the head size is the part that broke so now the helmet cannot be tightened and so it doesn't stay on and doesn't fit.  We went ahead and have now purchased a different brand.
