Jurassic Park came out in 1993 and tested the waters of Science Fiction and Thriller movie genres when it was released. What was supposed to be a family-friendly theme park presenting cloned dinosaurs to the public quickly becomes the scene of gruesome murders when the dinosaurs are released from their cages and begin to hunt the people in the park. This pajama features the Jurassic Park classic film logo. The pants themselves are made of a soft 60% cotton and 40% polyester fabric blend, for casual wear and lounging about!
