A lightweight hydration backpack is disclosed that can go under or over clothing and is hands free with tubes that work in the same way canvas straps work on a backpack making it easy to slip on or off. The tubes, which also double as left and right shoulder straps, deliver the liquid to the user along with supporting the weight of the liquid in the collapsible bottles on the back of the pack. The tubes can be easily released from the connectors by hand, allowing for easy cleaning and also allowing the user to cut the released tubes to fit his or her own torso size.
