BANGE Business Smart Backpack Waterproof fit 15.6 Inch Laptop Backpack with USB Charging Port,Travel Durable Backpack

Overall, it is a very nice bag. Very comfortable, it ties well to you. Intuitive pockets are well sized. Easy to adjust, it includes details that make a difference, like straps wraps that keep everything together and close to the body. Very nice, sleek design, and the fabric feels fine and unapologetically synthetic.

The only two points I would enhance are the bottom of the bag, which should be stronger fabric (you will eventually put the bag on the floor) and the overall rigidity, the pictures are deceaving in that the bag looks more rigid than what it actually is, it's not a problem per se but it may if you expect a more rigid bag.
Thank you
