This is my favorite bag. I love the high visibility color! This is perfect for hiking in the desert because of the contrast in colors! You can definitely see if you put this on a child during a hike. The quality is really good and fits a lot of snacks along with a water bottle. As long as you don’t make it too heavy it’s perfect fit and size for a child as well as an adult. Also very adjustable to switch the strap for preference.
