A backpack has a backpack body having a front panel 2 , side panels 3 , a back panel 4 , a top panel 1 , an opening for inserting equipment into the pack, a base portion, and a hip or waist belt 8 . The base portion has an inner panel 5 and an outer panel 6 . The inner panel 5 and outer panel 6 define a passage therebetween which terminates in side openings. A shoulder harness has two shoulder straps 7 . The shoulder straps are operatively connected to a flexible member 12 that is substantially non-compressible across its width, has a substantially smooth surface, and extends through the passage. The width of the flexible member 12 is smaller than the width of the side openings and extends through the passage via the side openings with portions of the flexible member extending upwardly from the side openings at an angle to the back panel. The angle of the upwardly extending portions is variable relative to the back panel to accommodate wearers having differing back lengths. The flexible member is substantially freely movable in a forward and rearward direction and a side to side direction relative to the base portion, over a range of differing angles of the upwardly extending portions, to enable shoulder movement of a wearer.
