Announced as the first waterproof backpack that opens like a travel bag, the ATRACK 35L from Ortlieb offers great prospects for outdoor adventures. The advantage of this outdoor model lies in its zipper closure that allows it to open along its length to greatly simplify access to its load. The large opening allows for a full view of the contents, while the nylon fabric design allows for front storage to keep the carrying system clean and dry. Offering protection from the rain, its fabric is complemented by a 100% waterproof TIZIP zipper. The zipper is also placed on the side facing the back, providing additional protection against unwanted opening attempts.Available in three sizes, this bag comes in a large 35-liter volume and is equipped with many functional details such as straps, pockets and pouches.
