You need to strengthen the bottom fabric or it will develop holes.
on 28 March 2017
These are cheap but the material at the bottom is very flimsy and if you accidentally pull it along the wrong way which is easy because of the design, holes will develop on just one trip. Even so, the proportions of the bag and particularly the outside pocket which is wide enough to take my small Macbook are good plus the option of using back straps. I bought another one and immediately strengthened the fabric by spreading strong glue on the bottom part then stuck 'ferocioualy strong' T-Rex duct tape on to it.
