ArC. 4 This bag is quite lightweight so it doesn't feel heavy even after putting my 13" laptop and other things in. Its design and function is very good, there are 4 ways to carry it and you can even keep the different handles in its own compartment. Delivery is very fast too, came within 1 day of ordering. The only reason I gave it 4 star rating is because of the bag material. There seems to be some white line stains on the canvas, and it's not part of the design. Makes the bag look very old instead of new and can't be removed. The color if the bag is also lighter than advertised in the photo
