Review on Stay Hydrated on the Go with Source Hydration Bladder - 3L Water Bladder with High Flow Storm Valve and Hydration Technology Advantages by Michael Welborn

This is Source's WLPS (Wide Low Profile System) hydration reservoir. After a long search I found the perfect reservoir for my 5.11 RUSH backpacks. This reservoir fits all RUSH packs, including the RUSH 12. A Velcro loop on the top of the RUSH bags goes through the clip slot to close the reservoir and attach it to the pack. The QD (Quick Disconnect) design makes it easy to detach and route the hose through the backpack and then connect it to the tank without spilling water. Another benefit of using this type of backpack is that this model doesn't come with a large, bulky filler cap. The tank has a partial internal partition to prevent "bloating" of the tank. But arguably the biggest benefit is that you can fill this reservoir without removing it from your backpack by purchasing an optional UTA adapter. The quality and design are excellent.
