A backpack comprising:
- a pack portion formed of flexible material having a top, a bottom, a front, a rear, and two sides;
- a stiffening member secured to the rear for stiffening at least an upper portion of the pack portion;
- strap redirecting members secured to the pack portion at upper regions of the pack portion on the sides and at the rear, a side strap redirecting member on each side, and at least one rear strap redirecting member at the rear which is also secured to the stiffening member;
- and
- a strap arrangement for carrying the pack portion as a backpack, the strap arrangement comprising a pair of carrying straps, each carrying strap extending from the bottom of the pack portion and extending upwardly along respective sides of the pack portion to movably pass through respective side strap redirecting members secured to upper regions of said respective sides, and movably redirected by the two side strap redirecting members to laterally extend around to the rear of the pack portion to movably pass through at least one rear strap redirecting member secured to upper regions of the rear, and being movably redirected by the at least one rear strap redirecting member to extend downwardly for securement at lower regions of the pack portion at the rear, the strap redirecting members movably redirecting each carrying strap while allowing the carrying straps to move through the redirecting members in a pulley like manner, the strap arrangement redirecting forces for supporting a load in the pack portion from the bottom and sides of the pack portion.
