Rucksack is a word derived from the German term Rucken. An English translation is back sack. And that’s a good description of the functional nature of a Rucksack, a sack for your back. Rucksack is an old term that represents a classic style backpack, maybe with a vintage design, like large prominent straps and a box rectangle bag. The Poler Rucksack 2.0 is updated for 2015 with new colours and improved construction, featuring modern fabrics, an external access laptop compartment, and a vintage design that draws on the Rucksack design language.
