I purchased this item for my son who is in the 4th grade.  The bag carries several notebooks, a large binder and two very heavy books; his usual load of homework.  The book bag has an excellent handle, and rolls easily. He has not had any difficulty with the zipper, as you may find with some other bags.  The navy blue color combination looks great.  We are both pleased with this purchase.

UPDATE, May 2012

My son has been using this bookbag for 17 months and it has held up extremely well.  He has continued to carry very heavy books and a combination of several notebooks, workbooks and other supplies.  No problems with wheels, handles or zipper.  No tears, or worn fabric. And, still looks great.  Excellent buy.
