About ALPS Mountaineering Caldera 5500 Backpack - Internal Frame

Closeouts. Designed for extended adventures -- the kind that may even include the kitchen sink -- ALPS Mountaineering's Caldera 5500 backpack offers a whopping 90-liter capacity. You'll be tempted to overpack, what with the extendable lid, spindrift collar, over-the-top compression strap and multiple side straps. When your base camp is set, the top lid conveniently converts to a fanny pack for a day hike to a ridge-top lunch.
