Nalgene is phasing out their flagship polycarbonate bottles over the BPA concerns. They've got a new line of bottles made from Eastman Tritan, a newer plastic. It'll be interesting to see if this leads to all the knockoff polycarbonate bottles eventually disappearing from stores.
Nalgene also has a new website, Nalgene Choice, that helps people pick the material for their Nalgene brand bottle. What's cool is that they feature the Guyot Designs stainless steel bottle. It has a Nalgene brand label on it but it looks like they didn't acquire the company. Hopefully that means we'll start seeing Guyot's bottles in more stores.
