Offering an innovative back system for improved stability and ventilation, the Patrol cargo from Source Tactical features a 35-liter cargo capacity. It comes with the low-profile WLPS hydration reservoir with a 3-liter capacity, drinking tube with Cool Weave cover, and Storm valve for straw-like drinking. The Patrol features a removable ergonomic waist belt for improved load distribution, plus padded shoulder straps with adjustable sternum strap and load stabilizers. In addition to the main cargo area, the Patrol has an insulated liquid compartment, two generously sized front pockets that are easy to reach, two hook-and-loop antennae ports, two cable ports, a padded bottom (that protects electronics), compression straps, and multiple MOLLE/PAL loops. The Assault comes with the 3-liter WLPS hydration reservoir (BPA and phthalate free), a low-profile bladder that's specially designed for ballistic vest integration. Source's Glass-Like Film is smoother than standard TPU films with virtually no difference from glass itself, preventing bio-film build up and making the system virtually self-cleaning. Source has been a groundbreaker in hydration system technology and is also well known for its tactical gear and hiking sandals. Tested in the most extreme conditions, hundreds of thousands of Source hydration systems are in use in the field.
