Sonata, the larger of our two sling bags, measures 8" across the bottom front, 11" top to bottom, and 2" in depth. Wide, fully adjustable strap makes this wonderful "bum bag" sit comfortably on the front or back, and is set off with a top tab of the contrast. Nice detail! The main compartment has a zippered pocket on the inside back, and you also have a zippered pocket the whole width of the outside back. On the front, two more zippered pockets, the top one being more than large enough for any phone.
