A backpack includes right and left shoulder straps that each respectively follows a path starting with a fixed connection at a bottom corner of a back panel. A padded portion extends upwards and then proceeds through an upper ring on the same side of the backpack. The strap then extends back down while crossing over to another fixed connection to a bottom corner on the other side of the back panel. At the top ring, the strap is merely guided back down and is not fixed relative to the ring. Curved frame stays on the left, right and bottom of the back panel have concave shape toward the user. A hipbelt attaches to the backpack with pin connections to allow rotational motion therebetween while preventing lateral motion. Outside straps reduce strain on the backpack fabric and side pockets are passthrough for insertion of objects therebetween while still allowing pocket usage.
