NATHAN Synergy Bladder Pack

This pack has the ability to carry water and electrolyte drinks in one bladder. In response to requests from runners who enjoyed the Nathan race vest, but craved additional and creative gear-carrying capacity, the Synergy has been 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.

The 3 litre water chamber has filter-compatible screw-top closure that is easy to fill, while the electrolyte chamber has roll-top closure that allows full access for easy cleaning and mixing drinks. The Potency Dial allows you to control intensity of your drink: all water, all electrolyte, or a combination of the two, and it easily and securely clips to either right or left shoulder strap at reinforced attachment points.

The zippered main compartment has a 750 cubic inch capacity, there are dual front pockets, one mesh holster, one zippered, and a Power Stretch Mesh back pocket for jacket or gloves.

Honeycomb Mesh shoulder straps add comfort, prevent chafing, and dissipate heat, while the lightweight, breathable Wall Mesh with soft perimeter binding feels great against skin and won't damage technical apparel.
