Ok- before I ramble on about this pack let me give you a brief idea of what I do; this way you can weight my opinion for yourself. I spend most of my time hiking, all over USA, backpacked through a few Central American countries, and now I have been hiking through the Alps on the Swiss-Italian border. I have hiked with some of the worst packs ever (military issue), so I have learned to appreciate some of the better packs out there. IMO MHM's Divide is one of them.
Hipbelt- While climbing up via ferrata trails the pack hugged my body very closely and moved well with me. It is also adjustable.
Pack Frame- Distributes weight very well, adjustable shoulder straps are nice. My previous pack (Arcteryx) did not have this feature, and no matter what I never felt like I could dial the pack in to me. The vent system on your back works very well.
Internal Pack Features- Love the built in rainfly, but it is not very durable (the pack itself is VERY tough). After some light use I was able to put a few snags in it, but overall a great feature and asset. The internal compression system is nice, giving you built in compression bags essentially. Great feature, but beware as this adds weight. There really are just lots of great features to this pack. There are many pockets and places to organize and store gear. The storage compartment at the top for your hydration bladder is convenient, but works best with smaller bladders. I used the Salomon Soft Hydration Bladder.
So the only thing you, the prospective buyer, really needs to beware of is the weight- if that matters to you. This is a heavier pack, but is the result of it being durable and feature rich. The most important thing to mention is the life-time warrenty. My pack came with a hand signed post card from the owner Jeff Popp. I e-mailed him with a few questions and comments and heard back from him within 24 hours. They support the troops as well! Great pack, great support.
