Considering the lack of belt height adjust ability I like the fit of the pack. It sits about right on me, but I have a short torso for a tall guy at 6'3". Belt straps are long and have no way to tuck them in so that is a minus here. I like the good sized belt pocket (some packs are to small to put an energy bar in and this is big enough for at least 2, big plus here in my opinion. One of the weak points is this only has two compartments, one for the avalanche gear (shovel, saw, probe, and just barely enough room for your skins). The other pouch is one large compartment for clothing and other stuff. There is a goggle pocket which is nice and a vented pouch in the main compartment. What would be nice to have in these bags in a dry compartment for cloths. At this point I just use a dry bag but it would be nice to have a separate compartment.
Another weak point is that when you use the helmet straps it blocks you from getting into the pocket with your avalanche gear, this is BIG HUGE minus in my opinion, and a serious design flaw. Time is or can be of the essence and the helmet strap isn't really easy to take on and off not to mention it will just roll/slide down the hill if you do when you're in a hurry. The second weak point is the main compartment is where you put your blatter if you use one and this should be seperated and ideally sealed if there is a leak. Not to mention the pouch for the bladder is a bit small and not really designed to work with any of my Camelbac bladders, my smaller Nathan running bladder works ok because it is smaller but there's no easy way to hang the bladder properly in the pouch. My opinion they should at least design a bladder to fit. Big minus points here again. I hesitate giving this 3 stars it probably should be 2 stars. I am going to keep the pack only because of the built in Avalung, which I hope works if I ever need it. I am not sure there's anything better out there but I would recommend that you look around.
