The Baloo boomerang is made of stiff foam for safe use even by early teens. It's also light and easy to throw for young arms. It is designed for any age 13 and above 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 have real air foils and great returners. And they are safe. An excellent choice for teens of all ages. Our favorite foam boomerang.
