The high performance Assault cargo pack from Source Tactical features a generous main compartment and an overall cargo capacity of 1220 cubic inches (20 liters). 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 Assault pack features contoured, padded shoulder straps for comfort, an independent suspension system with reinforced, ventilated back panel for stability, and adjustable hip belt and sternum strap. In addition to the main cargo area, the Assault has an insulated liquid compartment that’s easily accessed via a top zipper (with tube routing on either the left or right shoulder), side compression straps, a large external pouch and flat pocket for essentials, 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.
