Earth-saving and oh-so-hip, the Sigg 1-liter water bottle with a Retro Top is completely recyclable, plus it caters to your art-history loving side with a graphic of 25-cent Swiss stamp from 1881. Unscrew the sturdy Retro Top on this tough little aluminum bottle and drink on the go - you'll always have a fresh taste thanks to the non-leaching lining and the handy loop on top of the cap makes clipping your bottle to a pack or climbing harness.
