The Halftrack pack is similar to our G3M Phantom sniper pack; it's built from the same pattern as the Phantom's main pack. It's a front-loader, with two levels of varying-sized tuck-pockets lining its interior, Padlock system racks inside and out, and a fold-down shelf that can be used to divide the main compartment into upper and lower chambers. It will carry two 3-liter hydration kits, mounted in side pockets, or two 2-liter bladders in side-sleeves if you want to keep the main side pockets free for other gear. The waistbelt features a 6 x 2 Padlock matrix on each side. Sidewall tunnels allow carriage of long items such as skis or poles to be suspended from internal D-rings. A radio rack with large antenna portals is fitted to the back wall of the upper chamber. The pack features a robust internal aluminum and plastic frame, is comfortably padded with our deep-cut airmesh foam, and is well ventilated.
