Although designed to carry all the little extras that go with a laptop; cords, extension possible, external hard drive, or even a slim scanner, office stationery ... everything is in this bag! Please note it ended up being very heavy ... especially for 18 ''! Would recommend for computers with more than 17 '' for which it is sometimes difficult to find a bag to the right size. One negative: no reinforcements or protection or even small tabs to ask this bag vertically; is directly on the tissue! A plastic reinforcement was necessary as well as 4 small feet, this lack is really regrettable!
