I recently purchased a Sigg bottle that I'm very happy with. However, I just came across this site for the new Kor One reusable water bottle and I'm very impressed. Check out their site. The product is very cool and I particularly like the no screw cap which I can imagine would come in handy during my spinning class when we only have a few seconds to drink water or towel off. Buying bottled water is no longer cool. This is. Even if you recycle your water bottles, they don't all get recycled. On top of that producing and shipping uses up some serious energy (water's heavy) and contributes to CO2 emissions. So in the spirit of having a healthy body by drinking water, why not also contribute to a healthier planet.
