The Patagonia Black Hole Cube is a durable gear cube that 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 cluttered cab of your truck. It features a simple zip-opening design, an exterior daisy chain that lets you lash it to the outside of bags and a large, glove-friendly grab handle.
