Finally! An everywhere backpack whether heading out to the pool, lake, beach, kids soccer game or kayaking, you name it! This collapsable backpack is well constructed. The padded adjustable straps are a plus! Fits most everything I need for the beach, even includes a couple of reusable ice packs. This Koolbal backpack is a smart design, its water resistant for keeping your important stuff dry. Since we're pretty much a chemical free household, this cleans easily with Kangen 11.5 pH water used as a cleaner & degreaser and wipe it down with Kangen 2.5 pH water to disenfect for when your done as well. Another "Kool" feature, it can be used as a floating cooler, even comes with a couple of sports ball's for having fun with the kids and friends!I Going to get another one for my Godson's Birthday!
