Made of strong tear- and water-resistant ripstop polyester material, the 28 rolling duffel has durable construction and a spacious main compartment with a bi-fold bottom board to keep the bottom rigid with two inline skate wheels for smooth rolling. Measured at 28 x 12 x 13, 71.5-liter capacity, 2.4lbs, this wheeled duffel has excellent value and is available in-stores and online in navy and teal.
