The Patrol features a removable ergonomic waist belt for improved load distribution, plus padded shoulder straps with adjustable sternum strap and load stabilizers.

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.
