The F Stop Ajna backpack is generally well-regarded among travelers for its blend of comfort, storage capacity, and durability, especially for trips around two weeks. Its design is ideal for those carrying photography equipment, thanks to its optional internal camera units (ICUs). The size is a good compromise between carry-on compliance and adequate storage space.
Comfort-wise, the Ajna features adjustable shoulder straps and a padded hip belt, which helps distribute weight evenly across varying climates and terrains. The durable weather-resistant materials make it suitable for different environments.
However, the pack's organization might feel slightly limited if you're not carrying camera gear. If that's a concern, the Osprey Farpoint 70 or the Deuter Aircontact series are excellent alternatives, offering more general storage flexibility and similar comfort and durability levels.
Do you have specific gear you'll need to accommodate, or are you looking for more general packing advice?
