The Patagonia Black Hole MLC Cube Bag - 12L is an organizational bag for travel. The tough, weather-resistant, recycled polyester ripstop fabric holds up against the use and abuse of travel. Whether your adventure takes you to a warm or cold climate, this roll-top bag adjusts the size for the gear inside. The lower zipper compartment separates items from the main compartment, whether it's stinky socks or a jumble of charging cords.
