The 35-liter Allpa looks deceptively compact and is meticulously thought-out. First of all, this pack is super durable, so it can take a beating from trains, planes, and hostel lockers, and each zipper is secured with a theft-proof loop. It opens up completely, like a suitcase whose interior is divided into four mesh compartments—one larger compartment for clothing and bulkier gear, a medium-sized pocket that’s ideal for holding shoes or camera equipment, and two small pockets. There’s also a concealed pocket inside the largest compartment that’s perfect for holding valuables or a passport, a deep, subdivided exterior pocket on the front, and a padded laptop compartment that’s accessible from the outside of the pack and can handle large screens. Cotopaxi has even crafted a-la-cart accessories including a daypack that was designed to fit inside the Allpa, an exterior bottle holder, and a shoe bag to keep dirt at bay.
