I purchased this pack to replace a MacPac Torre that I used for several years with great success but it wore out, as things tend to do. I like the suspension that the pack has and is very comfortable to wear, for me at least, and still has some adjustment left, even though I am 6' 2". The pack holds weight well and expands past what I thought that it might. I haven't taken it out for an extended trek yet but anticipate that it will work well and intend to use it for a backpacking trip through the Mojave Desert in the spring. It can hold two water reservoirs, one on each side, and each side can hold up to three liters depending on the design of the reservoir. With it expanded, I can fit all my gear in it including a three person tent. If I was to need to pack it for very long treks, I would have to drop back to my one person tent but not a big deal. Material seems to be rugged and should stand up to some good abuse. Lots of adjustment on the suspension allows for personalized fit and better weight distribution. I would definitely recommend this to a friend for longer trek use.
