Bring along CamelBak's M.U.L.E. NV on your next medium to ultra long endeavour. Efficient and compact, this system totes 3 liters of liquid and 732 cubic inches of hauling capacity. Cargo space is wisely distributed and includes internal organizers for tools and gear. The ventilated, articulated NV back panel keeps the pack off your back and moving with you to keep you cool, dry, and make carrying water and gear merely an afterthought. The suspension harness adjusts to your shoulder width for a custom fit, too. The M.U.L.E. even has a weather-resistant media/electronics pocket, a helmet carrier clasp, and a stow-away rain cover.
