One night in the pristine wilderness can erase months of rat-race stress, but not if your pack strains your body or gets bogged down in back sweat. The Gregory Z40 Backpack doesn't hinder your outdoor therapy, offering plenty of airflow across the back, lumbar support, and a unique Dynamic Transfer Suspension configuration that increases in stiffness for proper load transfer. Light, ventilating, and efficient, the Z40 lets you get away from it all, but not at the expense of physical pain and suffering.
