I bought the Samsung 900x3g and it fits perfectly in this bag! On the inside, there is a tab in the you put into the laptop. As a result, water which should enter through the zip very difficult to penetrate to the device. In addition, the tab holds the laptop stable in one place. Well thought out and nicely solved! But I have the Cool Bananas ShockProof Pouch tasted sent back. While this seems more stable, but there is no water and no additional protective flap tray !! In the latter, I have the charger and a small mouse always with you! Therefore, the RainSuit was for me the better choice I would recommend this bag for the laptop at all times!
