Here's what other sites are saying:

Downright cavernous at a whopping 90-liter capacity, the Infinity 5500 holds enough gear for an extended backcountry trek-and more.


Specializing in week-long excursions, the ALPS Mountaineering Infinity 5500 Backpack comfortably fits all of your gear for long-distance treks into the wilderness. The pack's easily adjustable harness and waistbelt fit a wide range of torso and waist sizes, ensuring a customized fit with proper support for hauling heavy loads. The pack's spindrift collar allows you to overfill the pack on gear-intensive trips with its adjustable top pocket and "Over the Top" compression strap; additional side compression straps streamline bulky loads for easier hauling. Stuffed with plenty of pockets and organization options, the Infinity 5500 features a top-loading main compartment with a horizontal divider for smart, efficient packing. The pack's main compartment is accessible by a lower door, providing a great place for your sleeping bag. Adding extra functionality, the pack's front mesh pocket, hydration port and pocket, and side bottle pockets stash on-the-go snacks and hydration within easy access. In addition, the top pocket doubles as a fanny pack for day hikes, and the included rain cover protects your pack's contents from passing showers and storms.
