Had been looking for a ruck sack for a while but most were either too big or too small. This is 9 litres and perfect in every way. Quality item, enough room inside for a few items of clothing, food and tools.Water Botle included which for the price is excellent. Sits nice and snug and with the added waiste strap it feels really secure. Great item.
