A backpack including a pack portion having a top, a bottom, a front, a rear and two sides. A strap arrangement can also be included for carrying the pack portion as a backpack. The strap arrangement can have a pair of carrying straps. Each carrying strap can be secured to the pack portion at about the bottom and extend upwardly along respective sides of the pack portion, and redirected at about the top of said respective sides to extend around to the rear of the pack portion, and being redirected at about the top of the rear to extend downwardly for securement at about the bottom of the pack portion at the rear. The strap arrangement can redirect forces to support a load in the pack portion from the sides of the pack portion.
