Review on 🎒 Water-Resistant Travel Backpack: 25L Carry on Hand Luggage for 15.6 Inch Laptop by MATEIN - Flight Approved, Anti-Theft, Business Weekender Bag, Black by Mark Jefferson

This is what you need for ultra low cost/high downgrades in airlines or peon class in big corporations or whatever you call it to save some money. It matches the parameters of their "personal items". The bag will hold clothes for a few days etc. For most people it has room for your laptop/desk and good external pockets. It even has an external USB sleeve that can connect to a battery backup or charge something without taking it out of the box, depending on how you set it up. It even has a thoughtful zip and a place to store shoes without dirt etc entering the main compartment. It seems very well constructed with strong zippers and thick nylon. A good well thought out product that is well worth the money, especially if you are flying cheap.
