Why our gear experts love this
The ALPS Mountaineering Caldera 75 is your ultimate companion for multi-day hikes and backpacking trips, designed with the adventurer in mind who needs organization and accessibility on the go. With a generous 75L capacity, this pack is built to carry everything you need while ensuring that every piece of gear is within easy reach.
The main compartment features a horizontal divider to separate your essentials, while the lower section is accessible through a large, durable #10 zipper. Top-loading access with an extendable and removable lid lets you pack more for longer trips. Plus, that same lid converts into a convenient fanny pack when you need to travel light on short excursions.
The Caldera’s front wing lashing system houses a large front access zipper, allowing you to grab what you need without unloading the entire pack. With multiple side pockets designed to accommodate trekking poles and water bottles, hydration and stability are always within arm’s reach. Built for comfort, this pack features an adjustable torso length to ensure a custom fit for long-lasting support.
Recommended use:
Perfect for multi-day backpacking trips, extended hiking adventures, or any outdoor trek requiring substantial gear storage and quick access to essentials.
Bottom line:
Pack smarter, go farther—organize your journey with ease and comfort in every step.
