The NAVIGATOR BACKPACK 15L from Gomatic is designed to hold just the essentials, yet it can expand by 6L when you need the extra space. In the main compartment, you'll find more room than you might expect, with 5 mesh pockets and two zippered pockets, including an RFID-secure pocket. It also features a laptop and tablet compartment with a divider and a double bottom to protect your devices. The exterior of the bag has water-resistant, tamper-proof zippers for protection and security, as well as reflective strips for visibility in the dark. When you're on the go, the external straps help you carry a thing or two. You'll get two external quick-access pockets and a pocket for a water bottle that can be tucked away when not in use.
