Abstract: The invention is a water bottle intended primarily for distance athletes such as long distance runners. Internal to the water bottle is a series of baffles whose main body surfaces are located perpendicular to the longitudal (long) axis of the water bottle. The baffles are attached to the inner walls of the water bottle. The baffles are sufficiently rigid to arrest fluid motion minimizing the noise of water sloshing and energy loss due to fluid motion. The baffles are structurally attached to the water bottle in a manner that requires no central connecting structure and in a sufficiently rigid manner to arrest fluid motion during high intensity athletic events. The design may also incorporate a longitudinal baffle connected at near right angles to the previously described baffles or connected to partial baffles. Finally, the design may incorporate baffles that are non-planar (cup shaped).
