The Port Designs Courchevel 15.6 Clamshell Case is a sturdy yet lightweight bag, designed to transport your laptop. Its modern and popular style was developed by Port Designs' creative studio in Paris. This bag's clamshell design allows for the zipper to open up completely, going around the structural frame of the bag. This system allows you to secure your computer in the bag more easily using a hook and loop strap that will encase your laptop and prevent it from falling out of the bag if it is opened suddenly.
