I currently have the classic kanken backpack but it’s starting to break so I’m thinking about buying a new one. I am also getting a 14” laptop for school and I’m wondering which backpack would be a good size. I’ve been thinking about the laptop 13” and the laptop 15” ones but I don’t know if a 14” laptop would fit in the kanken laptop 13”. On the other hand I think that the kanken laptop 15” might be a little too big for me. Could anyone help me?
