High Sierra blue hydration backpack with water bladder, this one unfortunately doesn’t have the water bladder so you’ll have to buy it separately if you really want it, keeps any food or cold ice pack cooled or warm! Also picture 7 shows the back as you can see it also has air comfort for your back! Could be used for a hiking, riding a bike, field trips or camping. 6 zippers included, only 5 pockets and the other is shown on last picture on what it’s for! #hiking #outdoors #waterbladder
