Amazon Basics Classic School Backpack for Students - Durable Black Bookbag with Multiple Pockets for Laptops, Notebooks & Supplies | Perfect for College, High School & Travel

I bought this for my son when he was in PreK 4 (the year before kindergarten) and we finally decided he needed something with more structure because he has to carry a laptop. He's now in 4th grade. Absolutely nothing is wrong with it. No broken zippers or straps, no tears or rips. Honestly I can't believe how well it's held up from 6 years of daily use. In fact, now that I think about it, it will become his summer camp backpack.
