The roll-top backpack has been specifically designed for use on cycling tours or your next hiking vacation. A special feature is its variable volume. By simply rolling it up or down, the backpack transforms into a flexible space miracle. Thanks to the large opening, it is also particularly easy to pack. Inside, in addition to numerous pockets and compartments, there is a practical key clip. On the back, a padded compartment securely accommodates laptops up to 15.6 inches and tablets. Additionally, for those concerned about security, there is a hidden zippered pocket where items like a wallet and passport can be safely stored. The two practical front pockets and the small side pockets provide extra storage space and quick access to sunglasses and other essentials. Due to the breathable back panel, the particularly comfortable adjustable shoulder straps, and the practical chest strap, the backpack is ideal for longer cycling tours. The integrated attachment function also allows for easy fastening to the frame of a trolley.
