The Hydraform Reservoir 3L design presses an anatomically shaped molded plastic sheet within a nylon fabric layer and the back of the reservoir. This makes the reservoir fit to the shape of any ones back, even when it's full. The result is a solid and comfortable fit. The design makes it very easy to slide it in and out of your pack, as well as having a rigid handle/spine that secures the load of water. It is also available in a 2 litre size.
