I use the Camelbak 25 ounce water bottle as a way to drink plenty of water while not wasting a ton of money on bottled water and doing my part to help the environment. The bottle is a nice size, easy to clean, and comes in lots of colors. More important, you can get your daily recommended fill of H2O by drinking just 2 1/2 of these during the day. :-)

ps: This bottle is also perfect for short hikes with the dog or the Sig. O.
