I received a Platypus Big Zip hydration bladder for Christmas and I was really excited because of all of the features it has. The first time I used it I didn't wash it out all that well and noticed almost instantly that there was a pretty bad taste to it. Thinking that it just needed a thorough washing I took it home and used soap and water and thought I did a pretty good job. Used it again and it still has a really bad plastic taste. It seems like it comes from the mouth piece and kind of goes away when its really cold (I used it while x-country skiing last). I thought the Platypus bladders weren't supposed to have any bad taste, did I just get a bad one or is it just something that is inherent of all bladders or is there a way to get rid of the taste?
Thanks in advance!
