There’s been quite a stink over the bisphenol A in hard plastic bottles lately (yeah I know it’s sad the general public is just now learning about xenoestrogens), and I was wondering what you all use instead for water/protein shake bottles. My old nalgenes are getting rather worn, and I want to replace them with something lacking unpleasant chemicals if possible. I’ve been looking around and like the aluminum lined bottles. However, most models I’ve seen have a ridiculously small mouth that would make washing them impossible. Anyone know of a good company that makes the metal lined bottles with a reasonable mouth?
