CT3 Checkpoint Friendly Ultra 15.6" Backpack fits up to 15.6" laptops and features plenty of space for all your business essentials. CODi Checkpoint Friendly cases are designed to save time and eliminate hassle while navigating airport security. CT3 cases feature two distinct compartments hinged by military grade ballistic nylon which allow the case to lie flat while passing through airport x-ray machines and eliminate the need to remove the laptop from the case. Travelers can simply grab the case from the conveyor with one hand and go - the case secures itself with a zipper between the compartments.
