The Nomatic Travel Pack backpack is great for every occasion. Yes, there's enough room in the main compartment for books, lunch, clothes or whatever other work items you can imagine. Its computer pocket can hold laptops up to 16 inches in size. That's all well and good, but this bag offers so much more. It's expandable, TSA ready, water resistant, and offers a collection of external and internal pockets for all sorts of storage (including an RFID pocket for your credit cards). Small details like the retractable clip-on key leash and secret AirTag/Passport pocket make this bag a cut above the rest. And it's pretty nice to look at, too.
