The bladder itself is very well designed and my impression tasteless. Nevertheless, the taste when drinking water, even in water / juice blends was nauseating. As I found out on the Internet, is not due to the bladder itself, but on a lubricant, which is used in the mouthpiece. Supposedly you can also disassemble the body, clean, and then the problem is fixed. But, dear people of Hydrapak, let's be honest: I do not buy me such a hydration bladder, so I have to disassemble first time. I do not understand how this concept could mistake the final inspection happen! My conclusion: I'm using the drinking tube of Camelbak reservoirs (which also fit the Hydrapak Drinking bubbles), since there is not the problem.
