I've bought a few bottles of the series of Camelbak Better Bottle and was very happy with it. The 0.5 liter bottles also fit in the cup holder of my Beetles. And as a driver I have no drinking bottle in front of face, am not distracted by unscrewing a bottle, ... The new variety Eddy is barely higher and has more content, also fits in cup holder. And the thicker "straw" and the modified valve allow a better flow of water. I'm excited! Whether in the car, while shopping, while hiking, ... - the bottle is awesome!
