The number one rule of hunting is to stay quiet so the critters won't realize you're around. That's why we engineered the Reserve Hunt hydration system to be super-silent in the field...whether you're walking a fencerow stalking the rim rocks or perching in a tree stand. We use fabric that won't rustle with your movements so your whereabouts remain a secret.But the hydration system inside that water-resistant fabric is no less valuable to the success of your hunt. Because Gerber's patent-pending 70 ounce Liquifusion reservoir is re-writing the rules of backpack hydration. Its semi-rigid construction and anatomically contoured design combine to maximize comfort and prevent load shifting.The Reserve Hunt has easily adjustable straps an extra sternum strap for added stability and Velcro fasteners throughout. There's no better way to stay hydrated on the hunt.
