Well designed, Pictures provided don't do justice. Small Compact, comfortable lightly loaded. Build quality feels good/looks good. The front and back zipper pockets are extremely small (wallet would not fit either), and I suspect back is for padding primarily. The magnetic latch is solid, requires some force to open. The Belt strap is cosmetic, does not adjust. Large inner pocket is actually 2, one zipper and one open. The open is secure enough for a phone, and large enough for a 20oz bottle/thermist (but shapes the bag, and I find uncomfortable). The Zipper pocket, has a mini zipper inside (for cards/coins/ etc. ) and a pocket perfect for my wallet or phone, and open enough for additional small devices. The shoulder strap is easily adjustable and can be swapped for left or right shoulder.
