The Baloo boomerang is made of stiff foam for safe use even by kids. It's also light and easy to throw for young arms. It is designed for any age above 5 but, believe it or not, even top competitors like it as a warm up rang. As a foam boomerang these are even more susceptible to wind than most boomerangs, so don't even try them in anything above a light wind, but they are real air foils and great returners. And they are safe. An excellent choice for kids. Our favorite foam boomerang.
