Deliver electrolytes quickly and easily to stay fresh and cramp-free with a no-fuss system that works with your favorite–ade. Mazama's DUAL 3 L two-chambered reservoir puts both electrolytes and water close at hand. Just fill the chambers with your choice of fluids and you’ve got instant access to either liquid via the 2 shoulder strap mounted bite valves. This versatile reservoir features back-to-back 1.5 L chambers each connected a drink tube set. The unique top fill port opens wide for easy filling and cleaning of both chambers and positively seals every time with a flip of the twin locking levers. Made with a durable, taste-free film sourced from the USA, the system includes left and right drink tubes. Each bite valve features an integrated magnetic retention system for tethering to a pack strap. Quick connect exit ports make it easy to pull your bladder from your pack for fill-up while leaving the drink tubes on the pack.

An outdoor essential

This reservoir has become an essential piece of gear for me on long and sunny backcountry skiing trips. I fill it to 1.5 - 2L for a full day and alternate between water and electrolyte-mixed water, and it keeps me from bonking. I was surprised by how sturdy and easy this thing is to use, and it's already withstood a beating going up Rainier, squished to the back of my backpack by camping and avalanche rescue gear.

The only thing I would like improved would be to have the volume measurement be more reliable, and maybe have a separate scale on the back? I'll fill it with some water, and it'll show 1.5L, but when I add another .5L of electrolyte-mixed water to the other pocket, it will still show 1.5L. To make sure that I'm bringing enough liquids—but not carrying extra weight—I've been using a measuring cup to pour into the reservoir.
