I truly love this sling bag because it is just the perfect size for taking your most essential belongings with you whererever you are going. Although it is compact, the pockes are large enough to hold your important items . The front outer pocket is spacious and allows me to put both my iphone and my pocketjuice portable charger so that they are easy to reach when needed . I use this sling for our regular outings to SeaWorld San Antonio and it is just superb! Not too bulky that I am able to take it with me on the rides as well! I would most definitely recommend this backpack because it is small enough to hold your most prized possessions and still be comfortable while enjoying your day.
