While a teen girl might only care about looks, moms or dads buying a backpack want to be sure it's functional, too.

With the number of textbooks teens must lug around, it's also important to consider a backpack that will ease the load on a teen girl's back as much as possible.

You also need to take your teen's style and personality into account. Even if you are a total froo-froo satin-and-pink-lace type of mom, guess what? If your teen girl dons goth black all the time, she will think that cutesy backpack dotted with roses is ultra-lame!

Here are backpacks that are both cool and functional for back to school shopping.
