Plastic water bottles? SO last millennium. Stainless steel? Better, but early on some were found to have traces of unhealthy BPA. The next wave in safe beverage containers: glass beverage bottles from Lifefactory, an eco-conscious manufacturer. Covered with a grippy, completely nontoxic silicone sleeve and incredibly durable (I tested it out by dropping mine from about 4 feet up), these glass bottles are BPA-free, phthalate-free, and PVC-free, and have a wide opening, great for adding ice, citrus slices, tea bags, or whatever. And check out the fun colors! Another bonus: The whole thing can go straight into the dishwasher. Lifefactory already makes a glass baby-bottle version, too, and now these adult-size bottles are getting good buzz. Get one for yourself and a friend to stay hydrated this summer.
