Hmmm, so I was wary when I first heard of Nalgene / Lexan polycarbonate water bottles, what, three or four years ago? I mean, they have happy chemicals so they don't get gross-smelling? Happy chemicals that don't hurt us? It sounds too good to be true!

Oops.

So Canada's Mountain Equipment Co-op and the States' Patagonia have stopped selling products that contain bisphenol A.
