Our Aircontact trekking backpack has earned the predicate “unbreakable”. That’s why we decided on a gentle evolution: It is extremely robust, but comes tidier, more modern and slimmer with the trekking. And has become even more comfortable: Thanks to the new flexibly suspended Active Fit shoulder straps and the revised hip fins, the backpack hugs the wearer comfortably – for noticeably more comfort. For women, the new system has been equipped with the proven features of the SL fit. In addition, there is the new model 70+10 SL.
