The Cabin Max Laptop Backpack is another product which was developed from my own travel needs. Having to travel around quite a bit with my laptop I needed something I could use everyday, that was smaller than the Cabin Max flight bag but still big enough to get more than my laptop in. We therefore made a padded section inside the bag to keep your laptop cocooned and then made the material rain proof. (see video) . Making it rain proof also helps to make it appealing to photographers . SIZE 43cm x 34cm x 20cm = 30 litres.
