I had a quest: find a water bottle that won't hold smells, will hold up to abuse (especially in the delivery room!), and doesn't leach nasty plastic chemicals into the beverage I am consuming.
What I found was the SIGG bottle. This Swiss company has developed a water bottle that I really like. It is aluminum with a special coating on the inside so you don't have a smelly bottle or one that tastes like the sports drink you put in there some weeks back. It is also quite durable. In fact, Backpacker magazine dubbed SIGG as "The World's Toughest Water Bottle" in June 2006. That's good enough for me!
