The Vulture-II 3-Day Backpack is designed for hauling lots of gear. Endowed with 2100 cubic inches (34 liters) of carry capacity, 3 generous compartments, and a wide bottom design; this is the backpack to pack it all into. However, like all Maxpeditionition bags, size does not infringe on comfort. The Vulture II holds true to the Maxpeditionition ergonomic standard and comes equipped with comfortable back padding, curvaceous backpack straps, concealable chest & waist straps. The Vulture II also accommodates up to 100oz/3L hydration reservoir with bi-directional tube port (not included), and has plenty of exterior PALS webbing for attaching Maxpeditionition pouches and accessories. Great for longer hikes, deployment, or bugging out.
