KORIN FlexPack Multifunctional Flexibility Anti-theft Duffle Bag Backpack Waterproof Laptop Bag with 2.0 USB Charging Port Large Capacity TSA Travel Bag Friendly Easy Convenient Secure

This is the perfect as a carryon. Fits neatly under the seat. Also is great to take for a quick get away.

I really like the layout of this backpack! It's a well designed backpack featuring a large spacious central compartment that has a flap which can be completely unzipped. There is enough space for my 13 inch laptop as well as a tablet. The outside storage pockets are great for easy access items like sunglasses, keys or a cell phone. Inside there are a variety of pockets that accommodate anything from cables, chargers, flash drives, pens, and business cards to name a few. All the compartments are easy to see and access with very little effort. The shoulder straps are comfortable and can be adjusted. A convenient strap on the top of the bags allows for it to be carried when it is not on your back. The exterior USB port is a great touch although I found it a little difficult to access it because the tab on the rubber covering is a bit to small to grasp. When I was able to access USB, it worked fine. I enjoyed the TSA lock feature which is nice when the bag is not in your possession. The best part of this bag is that it is able to stand up on its own with or without a laptop. This was the most important feature that was lacking from previous bag. Overall a great travel backpack!
