These Babiators Rocket Pack backpacks aren’t made with PVC, a chemical found in many other children’s bags.  Instead, they are made from tough military-grade fabric to withstand all of your toddler’s indoor and outdoor adventures.  These adorable backpacks contain multiple pockets and loops for handling lots of fun gear, and a flexible, elastic chest strap to make sure the backpack stays on comfortably and securely. The Rocket Pack comes in one size which fits most toddlers and children ages 3-5.
