A hands-free personal hydration delivery system has a tubing assembly that has one end that detachably connects to a feed tube for a container of fluid worn on the back or torso of a user. The other end of the tubing assembly is coupled to a bite valve which is opened when manipulated by the user's mouth to allow fluid to be drawn by suction applied by the user, and is closed when not being manipulated so as to cut off fluid flow in an air-tight condition. An intermediate portion of the tubing assembly is mounted on the user's head or to the user's headgear at a position of higher elevation than the user's mouth. This allows fluid to be drawn to the elevated position and flow downward from there to the user's mouth by gravity feed. The fluid flow can then continue with little suction effort due to the gravity feed and siphoning effect of fluid from the container. The tubing can be mounted using retainer loops or other type of fasteners attached to a helmet, sports cap, head band bracket, headphone bracket, headband, or an earpiece worn by the user. The hydration delivery system is especially useful for bicycling, canoeing, mountain biking, kayaking, canoe paddling, and rowing environments.
