Backpack (Backpack / Rucksack / Knapsack)

City dwellers often toss essentials into a “backpack” for daily use. Hikers, however, prefer more rugged, framed packs known as “rucksacks” or “knapsacks” in British English. These bags are typically constructed from panels of nylon or Oxford cloth, cut precisely—often using computer-controlled knives. High-stress seams are reinforced with adhesive patches before top-stitching. Waterproofing is achieved through taped or heat-sealed seams. For comfort during long hauls, ergonomic straps are attached using reinforced bartacks and flatlock stitching.
