Mobile Edge ScanFast™ Backpack 2.0 – 17.3

The ScanFast Backpack and Briefcase 2.0 are made using GRS certified rPET main materials. rPET is largely derived from recycled water bottles and reduces greenhouse gas emissions by 79% when compared with virgin materials. This makes the ScanFast 2.0 cases not only smart for travel, but smart for the environment as well.

The TSA announced guidelines to allow travelers with properly designed carrying cases to pass through security checkpoints without removing their laptops. Mobile Edge responded by creating the ScanFast Collection, each case is uniquely designed to provide an unobstructed security scan of the computer. If you’re traveling with your laptop, let Mobile Edge make your trip through the airport security faster and easier, not to mention safer, keeping your laptop safe from thieves and from bumps. It will stay safe within your laptop bag.

Disclaimer: Given TSA’s use of random screening protocols, TSA reserves the right to re-screen any bag or laptop regardless of the design of the bag.
