The eTech 3.0 Carry-On Travel Backpack is a practical and lightweight carry-on solution. The main compartment has a large clamshell opening and has the same capacity of standard carry-on luggage. The quick-grab front organizational pocket is also surprisingly roomy and can fit all your packing extras such as a packable jacket, crossbody bag, chargers, pens, notebook, water bottle, snacks, headphones, and more.
