In 1898, Hans Deuter made mailbags for the South German postal service. Meanwhile the Deuter brand has grown to be the trendsetter among backpack brands, constantly in search of improvements in order to make wearing backpacks even more comfortable. For example, in 1984 Deuter developed the first truly ventilating backpack with the predecessor of the current Aircomfort system. To this day Deuter is leading in its use of new materials and techniques. Deuter is an important manufacturer of backpacks and has always constructively worked together with mountaineers. As independent technical advisors they offer Deuter their worldwide experience and their knowledge of product improvement.
