The Patagonia Black Hole Cube - Large has a simple design that plays a big role when it comes to organizing and corralling your gear so you can find what you need inside a stuffed duffel bag, loaded backpack or the scattered cab of your truck. The easy-access, main compartment opens with a clamshell zipper so both halves of the Black Hole® Cube can lay flat; each half is separated by zip-out mesh for organization. An exterior daisy chain lets you lash it to the outside of bags and a large, glove-friendly grab handle makes it easy to carry. This durable gear cube is made with a burly, lightweight 100% recycled polyester fabric and 100% recycled polyester lining that have a DWR (durable water repellent) finish.
