Right now, Amazon has a great deal for the High Sierra Loop Backpack in Black for only $26.42, shipped! This backpack normally retails for about $70. There are other colors available but the pricing may vary.
I like this backpack because it features several compartments and has plenty of room for books and binders. It even has a dedicated padded compartment to store a laptop or tablet, too! The dimensions are 19″ x 13.5″ x 5.5″.
This will ship for Free with Super Saver Shipping with orders of $25 or more. You can upgrade your membership to Amazon Prime and get Free 2-Day Shipping.
