The T3 Helo Ops Backpack is the ultimate helmet bag. Best of all, it was developed by the most cynical of all aviators: the helicopter pilot. For those who expect the worse, the T3 Helo Ops Backpack will help you cope with a planned or unplanned dismount. Made from 500d Solution Dyed Cordura, the backpack features an internal pocket that holds a PRC117G Radio/MRE/Mission 3-Ring Binder and a 100oz Hydration Bladder. On top of the pack are three external ports allowing for antennae and hydration tubes. The mesh pocket holds any size helmet with/without NVGs mounted. Plus, it’s well ventilated to let your helmet dry. The side pockets are large enough to hold Nalgene bottles, and the removable straps make it easy to molle into a plate carrier.
