The Pacsafe Metrosafe LS350 ECONYL Anti-Theft Backpack might look like an ordinary backpack, but it hides some extraordinary details and features. For one, the pack is made from eight recycled plastic bottles, meaning it is environmentally friendly. Also, it incorporates anti-theft technology, like RFID-blocking materials, slash guards, and security hooks and clips. Beyond that, the bag has a water-repellant shell and can fit a small laptop in the interior padded sleeve. This is an ideal backpack for shorter day trips.
