Don't get me wrong, the Camelbak system is great and is almost irreplaceable for certain treks. With that said, sometimes you just want a water bottle, of your choice, with a really long straw. Enter the Blue Desert SmarTube Hydration System, it is more advanced than a long straw but you get the idea. The SmarTube fits any standard water bottle and allows for hands free drinking. The SmarTube Hydration System comes with a 40-inch hose, a 63-mm mouth adapter, and a batch of special caps. If nothing else, it is easier to clean than my Camelbak, and cheaper at just $12.
