The first waterproof backpack that opens like a travel bag offers a new level of convenience for your outdoor adventures and short trips! 

Anyone who’s ever faced the task of having to quickly locate a particular item in the depths of a backpack will love the new Atrack! The Atrack outdoor backpack zippers open like a suitcase, greatly simplifying your packing logistics by giving you an at-a-glance overview of – and immediate access to – the individual items in your pack. You can also set the Atrack down on its front side to keep the harness system clean and dry. 

The Atrack not only spares you the inconvenient rummaging through your backpack, it allows you to do without a rain cover. No matter whether you get caught in a downpour or have to swim through a river, your gear will remain absolutely dry! This is because the pack’s PVC-free nylon material and TIZIP zipper are 100% waterproof. By the way, the zipper is located on the side that contacts your back, which also protects against theft in a crowd. 

The ingenious design of the active-travel backpack gives you maximum functionality when you’re out trekking, biking, ski-touring, canoeing, or rising to meet any other challenge in the great outdoors. The Atrack also feels right in the city and accompanies you faithfully as a streamlined pack for short trips. The Atrack comes in three sizes, three colors and an extensive range of accessories so that you can quickly customize it to your every adventure. Choose your favorite and start your story!
