Review on Source Outdoor Hydration Reservoir Transparent by Dwayne Meurer

I like the mouthpiece lid - the open bite valves on the camelbak hydration chambers pick up dirt too easily (especially if you drop the pack). The tank is easy to fill and hermetically sealed, does not leak. The entire assembly is also easy to disassemble for cleaning and storage. One part that took me a while to figure out is that you have to turn the mouthpiece counter-clockwise to open the valve and start the flow. This is a nice additional mechanism that reduces leakage.
