These latter two aspects are handled by the airscape accordion foam back panel and seamless lumbar to hipbelt body wrap. These increase the airflow, spread the burden and, along with the adjustable back length, provide a generally more comfortable carrying experience.  with a great design across the board, the bag incorporates everything from trekking pole and ice axe attachments to various quick access external pockets to go with the large main compartment. The whole bag can be compressed with the insideout straps, and any hydration reservoirs can be refilled with an external hydration sleeve and reservoir hanging loop.  with numerous other features, attachments and considerations, the talon 22 is a truly versatile hiking rucksack, one that you can depend on for years of service on your adventures.
