Hi! I'm a high school student, and I need a new backpack. I walk to school, and often on my way, my back hurts a lot because of how heavy my bag is, so I need a backpack that will help with that, but I also have to carry a lot ( 1 1-inch binder, 1 1and1/2 inch binder, four five-star notebooks, my 15 inch macbook air, a pencil case, a 40 oz owala, and a lunch bag) I was thinking of the TNF Borealis Luxe, as i've heard good things about it, but I thought you guys would be the experts lol.
