It is used for a Lenovo Yoga 2 Pro (13.3 ")
The Yoga fits in perfectly, less it is likely to be no more.
Interior is very soft plush.
The Zipp folds while opening to the outside so that the laptop while pack can not be scratched.
The small flat side pocket is just large enough to accommodate the power supply.
The only complaint:
The material attracts dirt and dust.
