I bought this pouch/sleeve case for my Sony Vaio (15") laptop 4 years ago. I have just replaced my laptop and am pleased to say that it is also the right size to house my new Sony Vaio (13.3")
The case is padded really well so that the laptop is fully protected. It has a velcro flap which seals the case. It is absolutely perfect for easily transporting your laptop without it getting scratched or damaged. Can easily be carried in your arms around college or university etc.
However the case only fits the laptop - power cables or leads need to be stored in another way. Whilst this does protect the laptop, as it means they will not be rubbing against it causing it damage - it does make transporting the laptop a bit more difficult (if you don't want to have to carry much). However, if you're planning on using it for protecting your laptop whilst it is in a backpack for example, it is perfect. Do beware though that the pouch is only padded and not reinforced so damage could be caused by heavy objects.
It's really go quality - has been used for 4 years and still in great condition!! Also lovely design which goes very well with the coloured laptops!!!
