My youngest child is a huge Star Wars fan. He doesn't like the show or the movie, but he loves the characters. When he saw this R2D2 backpack, he fell in love and had to have it for the new school year.
This backpack is very lightweight, but the weave is very durable and strong. It is quite obviously well made with good material and not cheap, easily destroyed material. This is important because my son is rough on his backpacks. It gets dragged on the ground, tossed down on the floor at the end of the day and just used continually. The best part of this backpack is that it lights up and makes little R2D2 sound effects. The biggest downside is the fact that if/when the battery dies for the light and sounds, I will have to cut the inside of the bag to be able to replace it. I don't like that. It would be much better if it was inside a little zipper or velcro spot so I could get to it.
Anyhow, it's cute and big enough for my second grader without being too big.
