When you are out riding your bike, hiking or engaging in any other outdoor activity do you use a hydration backpack to carry your water with you? Have you ever gotten back from an activity and found that your pack was full of water, but you were dehydrated since you did not drink enough?
Or worse, you ran out of water miles from home since you did not know how much was left in your pack and you did not ration your water accordingly? The Flow Meter from CamelBak might be the drinking aid for you.
