Stay hydrated while still in your tuck with Vision's Drinking System. This ingenious system gives you 2 separate 750ml reservoirs with independent tubes so you can customize your nutrition. Fill one with just water, the other with your energy drink. The top features a splash-free opening that makes on-the-fly refilling quick and easy, too. Its carbon body keeps the weight down and is corrosion-free. The aero shape won't slow you down and the highly adjustable mounts fit most aero bars, and make it easy to remove for cleaning as well.
