The Halftrack pack, like its World War II namesake, was inspired by necessity. The needs are fairly straightforward: carry heavy stuff, and make the thing that does it easy to use. The Halftrack pack is sister to the Phantom sniper pack, and is built from the same pattern. It's a front-loader, with two levels of varying-sized tuck-pockets lining its interior, PALS racks inside and out, and a fold-down shelf that can be used to divide the main compartment into upper and lower chambers. A plastic mesh flap on the rear wall serves as a radio rack.
