We have a variety of great carbon fiber / plastic composite boomerangs. These rangs are incredibly durable and consistent, although a little heavier than a normal rang and probably intended mainly for older teenagers and adults. As a more solid material they hold onto their tuning better but they are not for small children at all. So big kids only OK! The semi adult variety!
Our largest carbon fiber boomerang, the "Night Sky" is probably appropriate only for adults as it is a huge boomerang and heavier than normal. Check out the artwork on it though as it's great!
Some favorites include the Zebra and Quad Carbon Fiber boomerangs. Check out their boomerang videos!
