Get a refreshing drink of water even while wearing a full face helmet and sitting in a formula car. The 12" long flexible drinking tube on our drink bottle will even get around your head sock! A siphon tube inside the bottle extends all the way to the bottom, so you won't have to tip the bottle to get the last few drops. The translucent squeeze bottle is made of an odorless food-grade plastic that will not affect the taste of your water or sports drink. Holds 16 fluid ounces (1 pint / 500ml / 0.5l).
