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.

Verified Buyer Reviewed by musicmanley from West Virginia on Tuesday, June 27, 2017Couldn't be happier with my purchase. The pack is great 90L and the duffel bag type zipper is great for getting access to everything in the pack. With the clearance price and the timely delivery by Sierra Trading Post I would recommend to all my friends.
Verified Buyer Reviewed by Hollywood the hiker from Indiana on Monday, June 19, 2017What a bargain price for such a feature loaded backpack! The ALPS Moutaineering Caldera 5500 internal frame backpack is big enough to carry whatever you need for even the longest treks. There are pockets and sections that provide a place for everything. The best part is however the fit. I was easily able to make all the adjustments at the trailhead to give a comfortable fit for the backpack's first hike.
The included rain cover is an added bonus not found on most packs in this or any price range.
