NTG’s Take:
The Dinictis 40L Travel Backpack is perfect for shorter trips or if you’re bringing a separate suitcase or bag. It has plenty of room for a laptop and other things in addition to a good amount of clothes. You could actually use it as a day bag and leave the laptop sleeve at home. I really like the handles on the top and side which make carrying it very easy. The fabric is water resistant and durable to take the punishment of travel. It should easily fit in the overhead bin on most flights.
