Taskin brand backpack/suitcase. Small enough to use as a backpack (it has the back straps) but can be used as a suitcase. Great for Airplanes. Fits under the seat on an airplane easily and has enough storage for a nice trip. Many compartments. The dimensions are 19 inches long by 14 inches wide. It's an expensive bag and it's very lightly used. It looks better than the pictures. You wont be disappointed.
