No, not that kind of bladder! The CamelBak bladder! So I have a bladder that is 7 years old...no smells due to uncleanliness or bacteria, because I store it in the freezer when not in use (things don't grow in the freezer), but I do notice the smell and taste of plastic much more now. Anyone else have these issues? Are there any ways at ridding this smell/taste? Taste is probably what bothers me more. My guess is that the plastic may just be too old and that it needs replacing.
