Double Loop Flap-Over Laptop Backpack for Men & Women - Durable 15.6 Inch Computer Bag with USB Charging Port - Water Resistant Travel Backpack for Work, School & Commuting

Excellent quality backpack. Very roomy. I work in IT and carry a bunch of stuff around - Laptop, power supply, cables, tools, plus my aluminum water bottle (stop buying bottled water!). The side pockets are great for small items like your phone or a mouse or flash drives, etc. Multiple inside pockets too. This is very good quality leather so the pack is a little on the heavy side, and once I get all my stuff in it, it is no lightweight, but it does the job great. My laptop screen on the diagonal is 17 inches outside corner to outside corner, and it fits perfectly in the pack. If you want a good quality leather backpack that looks good too - buy this one.
