The first Berghaus rucksacks were launched in 1970 – the Berg 172 and Berg 272 models had external frames and basic single compartments. These more traditional sacks were followed two years later in 1972 by the Cyclops rucksack – arguably the world’s first rucksack with an internal frame.
In 1977 Berghaus became one of Europe's pioneer users of Gore-Tex® fabric, a new waterproof and breathable fabric.
This was followed in 1979 by the development of the Yeti Gaiter, whose distinctive rubber rands were initially made from old tractor inner tubes.
