The CODi Phantom CT3 is one of a handful of laptop bags we've seen recently that comply with recently released official guidelines from the TSA for creating laptop cases that can go through an X-ray machine with a laptop still inside. It's a potential win for any harried traveler who has ever been stuck at a security checkpoint, where, despite repeated admonitions, there's always someone right in front of you who forgot to take his or her laptop out of its case.
The $225 Phantom CT3 is stylistically similar, but much more expensive than the $99 Targus Zip-Thru Corporate Traveler. Both bags have two main compartments: one for your laptop, and one for everything else. The two compartments split open, butterfly style, so it can lay flat on the X-ray machine's conveyor belt.
