Light but very protective cover, dimensions to review

Cover featherweight! It's interesting, because this is not always the case. But suddenly it does not protect tremendously. It is rather a pouch to slip in a padded bag, only your computer is not protected enough against shocks.

The zippers are of good quality. But there are things to improve: the part for storing cable etc. on the side is too small, not enough space. My Mac Air 13 inch 'fleet of just under the skin and it is not top ... (it remains almost 2 cm of space on the sides and above when I put it in).
