The CamelBak BFM 3.0L Hydration Backpack is even larger than their popular Motherlode, but remains comfortable and mobile for high-performance outdoor and tactical use. It is made from 500 denier Cordura nylon for extreme durability, and features closed-cell EVA foam in the back panel and shoulder straps for enhanced comfort. Multiple external pockets make it easy to store and organize equipment, while MOLLE webbing on the front panel allows versatile accessory use. The full clamshell opening system allows you to open the bag completely for quick access to the contents, and the interior space includes dedicated areas for a MedBak insert or ASIPS Radio. The bag comes with a mil-spec 100 ounce Antidote reservoir, which fits into a dedicated foam-lined compartment that keeps it at the right temperature for longer. The PureFlow tube can be routed in multiple ways and is designed to preserve a fresh taste, while the Big Bite Valve provides quick, easy hands-free drinking. HydroLock one-handed flow controls lock the tube when needed to prevent flow, and the large fillport makes refills quick and easy.
