The Replacement 2.0 Liter Bladder is just what one would need for outdoor activities such as camping, hiking and so on. The bladder comes in the aqua-blue color making it a rather attractive addition to your outdoor equipment. The water pack is equipped with a long hose that makes it possible for you to sip water directly from the pack without having to remove it at any time. This saves you the hassle of carrying a water bottle around and getting it out for a sip of water each time you feel thirsty. The bladder can be easily slung on your backpack and refilling the pack is also ridiculously easy.
