Hydration is great, but so is ballistic armor. Now you can have both with the ArmorBak. Lightweight and simple to use, the Armorbak is deigned specifically to attach to the back of the IOTV, MTV or any other vest that offers a MOLLE/PAL back panel. Quick Attach Pressure Straps increase the flow from the low profile reservoir and stabilize the load. Includes the 100 oz (3 L) Mil Spec Antidote Short Reservoir.
