The Porter Force series features a military-inspired design with an occasional color difference in fabric. The fabric used in the front pocket and the fabric used in the bag itself is subtly colored different, making it a reproduction of the fabric that is rare to be seen in military goods. The bright orange color on the inside contract to the simple look of a military jacket. And the light and softness is a real first-class item. You will never want to be able to touch it with its fluffiness. Just the right size to fit A4 files, you can take it anywhere. There are also pockets on the sides, so you can easily take out frequently used items such as regular commuter and mobile phones. There is a removable pocket on the inside, so you can use it as a pouch to keep your essentials together.
