The OEM Kensington Contour Carrying Case (Roller) is designed for 15.4" notebooks. Its ergonomic design minimizes strain on the arm and makes rolling easy. This case is up to 25% lighter than most traditional rollers, making it easier to lift when loading into overhead compartments. The deep-quilted, impact-resistant notebook compartment with AirBrake bottom cushion protects your computer, while the external ticket pocket keeps important documents organized and accessible.
