Tastes like water, not plastic!
I finally converted over to the 3L Bigzip Platypus bladder after always using the Camelback brand bladders that came with my packs and would never go back. The difference between the water flavor (or lack there of in Platypus) is like night and day. The BPA free bladders by Platypus are easy to use, well made, and leave your water tasting like water instead of plastic! What an amazing upgrade!
