The Nordrok Folding Rucksack 20L is made from ripstop polyester material and boasts a clever design, helping to reduce pack size when not in use. But when needed unfolds in to a very usable 20 litre capacity rucksack. There are two elasticated side pockets for drinks bottles and flasks, along with a front zip pocket for personal possessions. The high vis detailing enables you to be seen at night and the padded adjustable shoulder straps, make long walks or holiday days out easy.
