The German backpack specialist Deuter, together with participating retailers in Germany, Switzerland and Austria, has launched a cooperation campaign with Lonely Planet until March 31, 2021: When buying an Aircontact Pro (men’s or women’s SL model), one of the brand’s trekking classics, the consumer receives a Lonely Planet guide of his or her choice, free of charge. The new Aircontact Pro is over 400 grams lighter than its predecessor and is designed for a total weight of up to 30 kilos. In addition, the trekking backpack offers high wearing comfort, as 70 percent of the load is transferred to the hip fins. The open-pored functional foam ensures a pleasant exchange of air with every movement. In addition, the new model is equipped with a bottle holder on the side between the hip fins and the packsack.
