POOR QUALITY -- wouldn't last one week in school!

I purchased this product for my 1st grader. He liked the design; I liked the Jansport brand (I have had several Jansport backpacks and always was very happy). Well, the backpack was so thin I could read this review online through the material. The backpack was so lightweight that my son's water bottle could put a hole through its side. The bottom had such little support that a wet paper grocery bag would provide superior results. In summary -- I returned the product the day after it arrived at my home. I actually contacted the seller and asked him/her if this was a knock-off, and he reassured me that it was a genuine product. Although I couldn't believe him completely, the vendor was very nice and professional about returning the backpack.
