It was specifically designed for storing clothing and features a double-sided, foldable configuration divided by an internal partition that allows for easy and space-saving separation of clean and dirty clothes. Access to the interior of the Travel Packing Cube is provided by the zipper panel. Pull tabs along the top of this zipper panel can be used to simultaneously pull the zippers while opening one panel to quickly remove or place items in the Travel Packing Cube. Although this Travel Packing Cube is intended for use as an internal pocket of the Travel series, it boasts a durable, weather-resistant nylon construction. An expansion zipper between its two zipper panels allows this Travel Packing Cube to increase its volume from 4.5 liters to 9 liters.
