I was looking for a backpack to carry the materials I needed for the technical training classes I am taking. The size of the laptop lent me to think that my 17 inch laptop might fit and it actually does but putting it in prevents me from closing the case. That is not the fault of of the seller as they stated the pack was for 15 inch laptops. The case easily holds everything I wanted it to and more with room to spare. It is comfortable to wear and or carry even when well filled.
