The Condor II hydration backpack is the dramatically improved second generation of Maxpedition`s military assault daypack that has been upgraded with the amenities of daily use in mind while not compromising the integrity of rugged battlefield construction. A square with rounded top design, the Condor II can hold over 1950 cu. in. of gear. One removable Y-shaped top strap and four quick-release lateral compression straps secure contents and takes strain off the durable zips. Wide shoulder straps with high breathability backing provides superb cooling characteristics. As with all Maxpedition backpacks, the Condor-II's loadbearing capacity can be expanded greatly with other MAXPEDITION modular pockets, added to the backpack's front or side PALS attachment points using Malice Clips. Although we recommend Camelbak hydration reservoirs, our hydration compartment is compatible with most aftermarket hydration systems.
