After 14 years with my last camelbak, I couldn't go with any other brand. There's actually nothing wrong with my old one, I just wanted the new bladder for easier cleaning and drying. I definitely recommend the cleaning kit to hang it and let it dry. So far, I love the new features of the bladder and the magnetic holder for the tube. The weather hasn't been hot enough to test out the air flow system, but it seems good so far. Very happy with it.
