The backpack fits the leappad, books, cartridges and headphones (a must for travel on an airplane). It's very durable and fits nicely on my daughter's back. She never whines about having to carry this one. It's the perfect size for the Leappad and accessories without everything bouncing around. Glad we got it. *The backpack is NOT educational of course, but to give it one star would shoot down the overall rating.
