The sleeve is made of durable PU foam that adapts perfectly to the shape of your notebook like a second skin. The best guarantee against surface scratches and other bumps and damage. The design is not only robust, but also extremely light. So your notebook can be transported flexibly without taking up much space in the bag. The sleeve is equipped with two zips. So you can conveniently charge your notebook or ultrabook without removing it from the sleeve. Another advantage: the zipper is provided with an additional surface on the inside to prevent scratches on the notebook.
