Snap pocket can be used to carry tickets, maps, Kindles, etc. Detachable padded adjustable shoulder strap can be worn as crossbody, plus the bag has a padded handle at the top for comfortable handcarrying. The bag lays flat or rolls up for easy packing into a larger case. There is a ring at the bottom of the main compartment to hold keys. Bag is approximately 13" tall x 13" long by 5" in depth.
