A backpack with a frame to carry a load. The frame has a pair of upright rails, one at each side of the hiker. An encircling belt is attached to each of the upright rails, and a pair of shoulder rests fit over each of the shoulders. Front and rear risers connect to the front and rear legs of the shoulder rests. The rear risers rise from the back of the belt, and the front risers connect to the upright rails. Balance rods extend forwardly from the frame and are vertically pivotable. They can lift and lower the shoulder rests. Forward load-attachment devices on the balance rods can carry a forwardly mounted load.
