This whistle should be considered an essential item of personal equipment for adults and children of any age. In my opinion, no kid should be allowed to go anywhere without a whistle, especially out in the woods. I suggest it be hung around the child's neck and left there. This whistles is lightweight, colorful and LOUD! They are perfect to wear on a lanyard and small enough to fit on your key ring. Comes in assorted colors. Purple,Black, Gold, Blue, Red , Silver & Green.
