Abstract: The present invention provides a rucksack comprising an enclosure for containing a load to be carried. A frame is attached to a back wall of the enclosure and shaped to hold the back wall of the enclosure away from the user's back to create an air gap. One or more web elements extend from a top portion of the frame to a bottom portion of the frame across the air gap. The rucksack also has a pair of shoulder straps with their top ends adjustably mounted on the web element(s) to be adjustable along the web element(s) between a first position nearer the top of the frame and a second position nearer the bottom of the frame.
