Perfect size for my macbook air. the pockets are very convenient to organise my other things. I can fit my wallet, keys, phone, a notebook, etc without it becoming bulky. I am yet to find a flaw with this bag, which is a very rare thing! Seems good for both everyday use and travel.
I am very rough with things and haven't had any problems with this yet. Fits my macbook very well and the pockets help for other things like pens and charging cables for phone. One thing I should add is it is hard to put the charging cable for the macbook easily in the bag, as it is quite a slim bag. But overall great quality and looks very nice in person.
