The Evader Military backpack hydration system from Gerber carries 100 ounces of liquid on your back with a bite valve positioned to rest on your shoulder. Gerber’s patent-pending semi-rigid reservoir design, called Liquifusion, is made from the same plastic you find in milk jugs, so it retains its shape whether empty or full. The reservoir is also contoured to follow the anatomy of your back to maximize your comfort while preventing load shifting. The pack itself is constructed of 1000-denier Cordura for rugged durability. Yet it’s capable of being very quiet, thanks to low-noise fabric available in four colors. Plus, the side pockets are very accessible, and the zippers are easy to grip. D-rings allow the Evader to attach to Molle compatible products. There’s also a one-inch Molle webbing grid on the front and back for multiple attachment options.
