Have for my Sony Vaio Duo 13 a bag searched, the not so closely located that constantly turns on by itself. It fits in perfectly, the exposed screen acts securely embedded and for all kinds of accessories such as power supply, mouse, wallet, etc. is still enough space. The only drawback, it is a bit high but that does not really fall. The material quality is also excellent and the design I personally like very well. The value for money is great.
