content: The product received was actually only 1L, not the 1.5L, and the top of the bladder has 2 wholes instead of the hook as the original camelbaks, so it is impossible to hang in the bag-pouch, which makes the whole bag uncomfortable...and since I had to order it to friends in the EU who were coming out to meet me in Africa, I have no other options... Should provide either a better description of the product, or revamp the product to be more compatible with it's intended use.
