Sport of hiking while carrying clothing, food, and camping equipment in a pack on the back.
In the early 20th century backpacking was primarily a means of getting to wilderness areas inaccessible by car or by day hike. It subsequently became associated with general touring by foot in urban as well as wilderness settings. Types of packs range from the frameless rucksack to the contour frame pack, with a frame of aluminum tubing and often a waistband that transfers most of the pack's weight to the hips.
