Quickly backfills up to 3 CamelBak Hydration Systems at a time. Drinking tubes can connect leak-free via two HydroLink Spigots located at the base of the SquadBak. The large 1/2" diameter fillhose can refill one additional reservoir via the fillport. Can be easily filled using the massive OMEGA fillport, or simply connect the 1/2" diameter fillhose to a water buffalo or a standard hose bib. Collapses for convenient storage when your mission is over and the system is empty. The SquadBak QL Conversion Kit allows the direct connection of Antidote and Crux reservoirs (sold separately.)
