Sigg's CEO has finally admitted that bottles made up till last year did have BPA in the liner. Newer bottles have BPA free liners. It should be noted that Sigg released "independent testing showing that its bottles leached no BPA in tests that mimicked liquids like colas, fruit juices, and water." But when asked if there was BPA in the lining they dodged the question...until now, almost a year after they've stopped using it. A casual observer might assume they waited so that they could sell the BPA lined bottles and not be stuck with them-- is that an awful thing to say?
I love my Kleen Kanteen- it is made from stainless steel. No liner needed. I also have a knock off Sigg at home that is a couple years old, and am pretty sure it has a lining with BPA. I'll still use it, but will avoid hot liquids (not that you want to put those in an uninsulated metal bottle anyway!) and will probably recycle it in another couple of years.
And by the way, is a BPA lined Sigg still better than plastic bottled beverages? Heck, yes!
