Patagonia’s entire Black Hole line sells like hot cakes at REI. It’s hard to resist this workhorse weekend travel bag all laid out in shiny colors like big pieces of candy. No wonder people can’t get enough of them. The burly travel bags, which range in size from 40 to 100 L, are made of weather-resistant recycled polyester ripstop fabric overlaid with a special laminate and a durable water-repellent (DWR) treatment to bust more moisture.
