Two Tripped compression packing cubes. Made of durable, tear-resistant ripstop nylon. Approximate measurements Grand Canyon cube 10.5” x 7.5” expands to 3”, Yellowstone 14.5” x 9.5” expands to 3.5”. Good used condition. Originally part of a larger set, but I no longer have the other bags, only Yellowstone and Grand Canyon. Last photo is a stock photo to help show how they work.
