Review on 🎒 Versatile 15-16 Inch Laptop Backpack with USB Port - Slim, Expandable, and Spill-Resistant - Ideal for MacBooks, Surface-Books, Dell, HP, Lenovo, Asus Computers - Gray Orange by Sean Burnett

A backpack can be thin and travel-friendly, or you can expand it to hold many things without feeling like a backpack or looking bulky out. It has decent storage capacity and different partitions for organization. The laptop compartment is well padded. The only thing is that the laptop zipper is on the outside. But I really like this backpack and I don't see any other that is as thin and expandable as this backpack and can hold a laptop. The price is also very reasonable. I don't know how waterproof it is, I haven't tried it.
