When Gerber set out to craft a specialized hydration system for serious hunters, they knew better than to settle for simply being stealthy. So they engineered one that can be worn in four different configurations. (And yes, the pack walls are made of a nearly silent fabric.)

• Option 1: Hydration pack alone
• Option 2: Waist pack with harness
• Option 3: Waist pack alone
• Option 4: All pieces worn together

Another innovation on the Quadrant is the patent pending sliding lumbar pockets. They ride around back and out of the way. But when you need to access the gear inside, the pockets slide to the front. Plus, the easy-pull zippers operate quietly. Finally, the Liquifusion™ reservoir is made of semi-rigid plastic that holds fast to the contours of your spine, carrying your liquid refreshment effortlessly.
