"The Up In & Over Dinosaur Bop Bags are inflatable punching bags for high energy, Jurassic-loving kids. The three assorted options are inspired by the T-Rex, Raptor and funky-headed Parasaur. These bags are built for punching, kicking and tackling - yet they’re incredibly safe and possibly therapeutic for rambunctious boys and girls.

The safety valves provide air retention during the bop bag action while speeding up inflation and deflation. ""Inflatable punching bags for unlimited bopping action!
