In addition to the generous internal storage, the Manta XL also includes a quick access external storage pocket, quick-view smartphone pocket and integrated audio port. Other details include a convenient removable shoulder strap and ample reflective striping. This bag measures 15-by-8-by-4.5 inches and retails at $84.99.
