Bamboo bamboo bamboo. I get it. Its written on this damn bottle four times. I know, its gonna save the world. Im not against bamboo, but Id rather focus on a far more important component of this water bottle: air. Plusses Between the Leed-ready bamboo shell and the deliciously nonporous glass liner is a layer of air. The great insulator. And the shit works as advertised. On a steamy NYC day, I still had traces of ice cubes jingling around in there after 2 hours. Also, the bottle comes apart in a jiff, and every layer except the bamboo is dishwasher safe. Nobody likes a manky water bottle.
