Ortlieb Atrack Designed with modern, active travel and minimalist style in mind, the innovative Atrack is the first of its kind. The uniquely positioned TIZIP zipper inside the Atrack’s back provides a wide opening offering unobstructed access to all of your gear, no matter how crowded your pack is. Another bonus: the carrying system stays dry and clean during packing and unpacking, because the rucksack component of the Atrack lays face down on its front. The zipper‘s unusual and strategic position is another advantage: it prevents any unauthorized access while the pack is on your back. The Atrack is both, a full-featured outdoor backpack and a travel duffle – offering maximum flexibility with just one piece of luggage. The modular system and numerous accessories allow individual adjustments and quick, sport-specific modification of the pack along your trip. Shoulder straps with stepless length adjustment allow individual adaptation of the pack to various body sizes. A breathable carrying system and a padded waist strap with integrated pockets ensure ideal distribution of weight and optimal ventilation. Four zippered inner pockets and internal compression straps guarantee clean organisation for easy packing and unpacking.
