Time to reverse that old chant -- during the dog days of August, when families start their back-to-school shopping, "no more pencils, no more books" makes way for "brand-new pencils, brand-new books." And, of course, kids need something to keep all those pencils and books in.

Which often means a brand-new backpack.

Here are some backpack suggestions for every age.
