This medium Travel Packing Cube from Peak Design is part of a compartment system that enhances the ability to organize the contents of a Peak Design Travel-series bag. Specifically designed to store clothing, it features a double-sided, clamshell configuration that is divided by an internal partition, allowing easy and space-efficient separation of clean and dirty clothes. Access to the Travel Packing Cube's interior is enabled by its zippered panels. Pull-tabs along the top of those zippered panels can be used to simultaneously retract the zippers while opening a panel for immediate removal or placement of items within the Travel Packing Cube. While intended to be used as an internal Travel-series bag compartment, this Travel Packing Cube features a durable, weather-resistant nylon construction. An expansion zipper between its two zippered panels allows this Travel Packing Cube to increase from 8L to 18L in volume.
