We love dinosaurs in this house, so when we see MadPax backpacks that turn kids into dinosaurs we say "yes please!". The colors are so vibrant and fun, and the material soft and flexible. The backpacks come in several sizes: full packs, half packs, nibblers and mighty bites. The full packs look enormous on toddler backs, so I think I'll wait until the little guy is a little older to get him one, but that day will definitely come. He'll "stick out" from the crowd when he goes to school!
