I've just learned about a product recall by SIGG, which makes cool reusable water bottles, sold at places like REI, Whole Foods, New Seasons, etc. I've loved the lightweight, durable bottles with their fun designs and bought some for my whole family. It turns out there is some question about their old liners and BPA-leaching. if you have SIGG bottles and are concerned, check out the following link for more info. There are photos there of both their old and new liners, and you can see which you have. Ours were old, so I called REI where i purchased them and found out they will exchange the bottles at their stores. Whole Foods will do the same. Or you can download return forms from SIGG and get an online coupon for a new bottle on their site.
