Touch here to read this entire Review: "I can not recommend this pack enough. As a Scoutmaster for ten years I had an opportunity to try and to see all sorts of external and internal frame packs. This is the best, hands down, in every category. Why do I love this pack – Comfortable. No other pack is nearly as comfortable as this. I loaned the pack to my son’s girlfriend for her first backpacking trip ever – they came back engaged!! At Philmont... " Tom L. September 2014
The StackPack is the lightest 50+ liter 50lb capacity backpack you can buy. Why? Most people think cloth is lighter than aluminum. Not true. To deliver the same amount of structural support, a fabric/foam structure will weigh about four times an aluminum tube frame. And aluminum tubing is lighter than titanium and totally strong enough for a backpack. The breakthrough Hook Belt™ and individual waterproof fabric Barrel Bags makes backpacking much more fun. Your gear stays organized and accessible inside the individual Barrel Bags. You can keep all dirty/wet gear isolated from food, cameras, clean clothes. Adjust the waist belt once to the perfect fit and leave it that way all day long because you can slip the frame off and on the Hook just like a beltless rucksack. Your torso length does not matter because telescoping frame adjusts from 20 to 32 inches. You can seup the shoulder straps so there is no compression weight on your spinal column. The StackPack is very comfortable because it is COOL... no insulated pads making your back sweaty and irritated..
"Four or five years ago I got a LuxuryLite pack from you and it has extended my outdoor career far longer than my aging back deserves." Frank Z. 3/2010
All the weight of your gear inside the Barrel Bags rests on the shelf at the bottom of the frame. And, you can set any food canister on that shelf with the Barrel Bags stacked on top. The velcro loops that hold the Barrel Bags to the vertical frame tubes are not weight bearing so we can use ultralight fabric without tearing. The Hook Belt supports all the weight while the shoulder straps keep the pack stable, but loose, comfortable, and cool. The Hook Belt means you can set your pack down anytime, anywhere without the waist belt dragging in the dirt, mud, and poison ivy - and it stands upright and rainproof.

The Barrel Bags can be removed in a few seconds to use inside your shelter like duffle bags. Barrel Bags are made from fabric that is light, tough, and waterproof. You can float this pack across a lake and nothing gets wet. Each Barrel Bag has a full-width Velcro closure (no zippers to jam and leak) that makes access to all gear fast and easy. The frame's vertical side rails extend one inch above the horizontal top tube so you can hang the Front Pack, hiking poles, dog leashes, etc.

You can slide the shoulder straps right or left along the frame top tube (even while walking) to perfectly fit your shoulders. The waist belt can be set easily from 24 to 44 inches with a moveable Velcro strap. There is no click-to-open belt buckle; you can change the snugness of the belt by fractions of an inch for optimum comfort. Our Barrel Bags will hold a lot more gear than a typical internal frame pack rated at the same cubic inches. Because there are no wasted corners and no double-counted external pockets.
