Hydration during your shock and awe moments is made easy with the Mil Tac MULE 3.0L (100oz) Hydration Backpack from CamelBak. Durable fabric (500D Rip-Stop Cordura fabric) and construction make for a worry-free mountain scale, dessert hike or hunting excursion. CamelBak makes it easy to control your water intake with a patented hydration system including insulated PureFlow tube, Big Bite Valve, Quick Link Exit Port and Drink Port, QL HydroLock. Refills are simple with the large mouth opening and the design renders cleaning effortless. Life on the trail was never more organized using the MULE compartments and MOLLE grid, and the Air Director Back Panel allows for the escape of body heat in extreme temperatures. The weight of your CamelBak MULE at 1.9 pounds does not add to the water weight gained by up to 3 liters of liquid.
