Comments about JanSport BIG STUDENT BACKPACK: I have had the same Big Student backpack since I was in 2nd grade. I'm in 9th grade now, and there is no sign of wear whatsoever. In 8th grade, I was sent home with lots of homework. I love this book bag, and I definitely plan on coming back this year for a new one!
