The Caldera's main compartment has a horizontal divider to keep your gear organized and easily accessible. The lower portion of the pack can be accessed quickly from the large #10 zipper. The main portion of the pack can be loaded from the top with an extendable and removable top lid, that doubles as a fanny pack. Behind the front wing lashing system sits a generous front access zipper allowing you to find exactly what you need without unpacking everything. The side pockets offer room for trekking poles and water bottles to keep you hydrated.
