The Patagonia 14L Black Hole Cube Bag is made from burly recycled polyester ripstop with a matte, weather-resistant, recycled TPU-film laminate. The main compartment is divided equally with zippered pockets; one side is mesh for easy visibility, and the other is taffeta to fully separate dirty items. Over it exterior daisy chain for lashing onto packs and racks or clipping onto duffel bags with large grab handles or plastic zipper sliders for corrosion resistance in saltwater applications. Fits inside Black Hole duffels for seamless packing; cube volume is 14 liters and big enough to hold bulky items, like a pair of shoes or a week's worth of laundry. Made in a Fair Trade Certified factory, which means the people who made this product earned a premium for labor.
