Nathan Synergy :
Mixed drinks aren’t just for post-race anymore. Finally, the ability to carry water and electrolyte drinks in one bladder. In response to requests from our ultrarunners who loved our race vest, but craved additional and creative gear-carrying capacity, the Synergy is designed for the runs, rides, and hikes when you need more than just water. The unique Synergy Bladder carries water and electrolyte/energy drink in separate chambers, and the Potency Dial allows you to choose pure water, electrolyte drink, or your preferred combination of the two throughout your adventure.
