Ever wonder how much water is actually left in your Camelbak®? Now you’ll know for sure with the Flow Meter™, which converts any CamelBak® reservoir into an intelligent hydration system with a gague that measures how much water you drink and how much is left. It also allows you to program your personal hydration goals to help prevent dehydration. You can buy the Flow Meter™ already installed on a Camelbak® reservoir, or you can easily integrate it with an existing reservoir. $30 camelbak.com
