With our book-loving son in mind, we wanted to create a pack to open just as his many books do… flat. With this accessibility, it promotes organization, easy cleaning, and access to all of your necessities. The Arrow Pack has three compartments with easy pull tabs, 2 pen holders, padded section for an iPad or 13" laptop and a larger pouch with a buckle closure. A perfect carry for the simple packer, the adventurer, the book lover.
