If you can, try out a laptop backpack in person. For example, if you’re shopping in a brick-and-mortar retail outlet, you should be able to examine the entire backpack, inside and out. When you do, look at the quality of the stitching inside of and on the exterior of the backpack. High quality backpacks won’t have slapdash, uneven or sloppy stitching. Also, make sure all zippers are protected with flaps of fabric, a design feature that prevents water from seeping into the interior of the backpack. At the same time, you should also try wearing the backpack and see if it’s comfortable or not.
