Ortlieb Notebook Insert 17" is where data protection starts. The EVA foam which is covered with nylon fabric protects from shock, impacts and crashes. The indispensable transport assistants are just as versatile as the laptop that they protect. Horizontally they fit inside Office-Bags, Zip-Citys and Sling-its (except size XS), vertically they protect equipment inside backpacks and messenger bags. Covered zippers with adjustable and positionable inside corner pads prevent damage. On the rear side the sleeves have external organizers with slots and zippered pockets for important accessories like pens, CDs and USB sticks. The external pocket with folders on the front offer storage for power cord and other small items.
