From the Manufacturer:
A radical twin compartment Bodypack that reduces weight without compromising biomechanical principles.
The Natural Balance will carry 10 days of ultralite gear. For lighter loads, the two liners can be removed (dry climates). For a true comparison with competitors' products, add the weight of a plastic liner bag and sleeping bag stuff-sack to their products as these are standard with the Natural Balance. Now with waterproof Expedition Balance Pockets.
It has received many outstanding testimonials and the DuPont Brand New Award, Germany and the Adventure Gear Guide Innovation Award, Australia.Key Features:
