The reservoir design sandwiches an anatomically shaped molded plastic sheet
between a layer of nylon fabric and the reservoir back. This forces the reservoir to conform to the back’s complex shape, even when full. The result is a more precise, stable and comfortable fit. Additionally, this reservoir has a rigid handle/spine that stabilizes the load of the water while also serving as a more convenient design to slide the reservoir into the pack.

• Built to pharmaceutical biocompatibility specifications to assure taste and odor free hydration
• Contains AquaGuard™ anti-microbial formula to prevent bacteria and mold
• BPA and PVC free

The HydraLock™ internal frame provides a dedicated space for the reservoir, so that cargo volume is not affected by a full reservoir. It effectively squeezes the reservoir, supplying hydraulic pressure to increase the flow and minimize water motion. It also provides a perfect anchor point for the vertical spine of the reservoir, preventing lateral instability and locking the water load in the overall pack structure. The reservoir is further compressed at the top end with load lifter straps. This keeps the pack stabilized during recurring and unexpected motion.

A BioStretch™ harness and hipbelt are made with mesh covered die-cut foam that allow free body motion with minimal pack bounce. The chest strap is elastic and includes a magnet for quick bite valve attachment
B The backpanel is made with ventilative EVA foam and mesh
