You might want to replace the image of the old style Nalgene bottle with a newer Nalgene because the old ones with the whiteish color had BPA whereas the newer ones do not. A lot of people, including myself, replaced the old ones when the media pointed out the BPA danger.
I think this a picture of the soft HDPE Nalgene bottle. I think some of the hard ones had BPA but never the soft one (it’s a plastic hardener after all). Nalgene now says they don’t use BPA in any of their bottles.
