Rated 4.3 out of 5 by 18 reviewers.
Rated 4 out of 5 by Awesome Heavy/Family Hauler I am a self-acclaimed family expedition guide. Recently my wife (5 months pregnant) and my 3 year old son went to Havasu Falls, AZ. It is a 20 mile round trip trail in the Grand Canyon. With my wife being pregnant and my son too young to make the journey without any help, I was left to carry everything including him for a 4 day adventure. At the end of the day the pack weighed 100 pounds! I have carried this before but with the ridged main stay and large main compartment it was the most comfortable I have ever been under that amount of weight. Since that I have also logged other hikes both day and longer expeditions and have always turned to this pack. I really like the number of stabilizing straps, there are just enough to tighten down large loads as well as condense the back to be used a day pack. I do wish the lid could turn into a small "peak pack". This would make the peak day more enjoyable versus lugging the whole pack up to the top. Also the outside water containers are hard to get to with the pack on, however the size is nice to cache gloves, hats, glasses and any other misc. items not needed but keeping them close.

Rated 4 out of 5 by Solid Pack for the Price I have owned this pack for about 3 years now and have put approximately 1200 miles on it. Never have I carried less than 55 pounds and have carried up to 85 pounds over sustained time periods. The Good: 1. It is truly a minimalist pack, compare it to similar freight haulers and you will see a significant difference in weight. 2. It has plenty of room to sustain oneself indefinitely in the wilderness. 3. Being as rigid as it is, it does an outstanding job with load bearing. The Bad: 1. The lumbar pad is very rigid, though this was not a significant issue for me. The greater issue was the hip belt, it could definitely use more padding. I would often be rubbed raw on my hips. 2. Ice axe loops could be better positioned. 3. There is no easily accessed water pouch. August 28, 2013
Rated 5 out of 5 by Excellent large hauler Excellent (relatively lightweight) large hauler. Comfortable on many mountains carrying heavy loads. I've used it so far up to about 60 lbs. and it felt like 40. Cavernous bottom zipper section holds two sleeping bags and even a small inflatable pad. Ice axe system is a little awkward and overly technical. Not sure why MH didn't keep the traditional loops on the bottom (might've saved an ounce or two as well). Lastly (and least important), I believe the "Large" size is actually 115L...this might be excessive - I'd rather retain the 105L size. July 27, 2013
Rated 3 out of 5 by It has the potential to be so much more... I used the BMG on Denali this spring because it was the lightest pack on the (mainstream) market for the given volume. Unfortunately, there were a number of small issues with the pack that I think could easily be eliminated: 1. As mentioned in another review, MH does not allow you to mix and match waist strap with pack body, meaning I had to shell out another $60 for a pack to fit my body (if you go on other sites, you can get the waist strap for substantially less, although its for the older version of the pack) 2. The padding in the lumbar region is EXTREMELY stiff. It left bruises on my lower back. Not sure if the stiffness is for load transfer, but it needs to be reconsidered for the next model. 3. There's no "traditional" ice ax loop near the bottom of the pack. MH support was great in getting back to me and showing me how they thought an ax should be carried, but it seemed a bit off to me. In the end, I made my own ax loop by attaching it to the bottom compression strap buckle (where you would normally attach a closed cell pad). 4. The lower compressions traps were to short to attach a Ridge Rest, so I had to add my own. 5. The water bottle pockets seem at odds with the rest of the pack's design choices. It seemed overly burdensome--I had to compress two straps just to get a drink of water out. In the end, I appreciated MH's minimalist approach to this pack. I understand that there really is no way to COMFORTABLY carry 50-60-70-80 lb loads (although the Denali Pro, which I used for several months, seems to carry loads a little better, but at a cost of about 2.7 lbs). However, I know MH has it in them to build a better pack, without substantially increasing weight. May 29, 2013
Rated 5 out of 5 by Perfect Big Load Hauler Purchased this pack in December 2012 for Denali climb in May 2013. Have used it twice on prep climbs. One on Mt. Hood, one on St. Helens. Both trips I loaded the pack with about 40lbs of gear, food and equipment. The sleeping bag compartment is a nice feature, as is the ability to really compress the load with the side and front straps. I'm 6'2" and have the "large" size - fit perfect and felt very comfortable . March 7, 2013
Rated 4 out of 5 by Great pack I really liked the pack. The pack can carry heavy loads well. I would have given it 5 stars if it wasnt for the chest strap/clip, it is not secured to the pack and falls off. I lost it so now im looking for a remedy. should be a simple fix. Great pack!

Rated 4 out of 5 by Great Pack - Watch out for Belt Size What a great pack and does great carrying a 70 pound load - - good weight transfer to the hip belt. Watch out though for the belt sizing. I needed a Medium sized pack but the hip belt wound up being too small to go around my hips. Since you can't choose a belt size, I wound up having to buy another belt a size up - - cost $57 which starts to make the pack very expensive. January 25, 2013
Rated 5 out of 5 by Best value big pack out there Everything that you need in a big pack and no more. Not quite minimalist, but very simple and well made, but it still has just the right number of pockets (big main, plus sleeping bag and front pocket, plus few key stash pockets) and features. I especially like that when you remove the top lid, there's a flap with pockets that still covers the top which significantly reduces the size of the pack for shorter trips. The pack compresses down well when it is not full. For me it rides well and is very comfortable. Even so, get yourself in shape because it is so large that it will still be heavy when it is stuffed full of all of that stuff your family wants to bring along but does not want to carry themselves.

Rated 5 out of 5 by IT'S A MONSTER! I bought this pack for 3-5 day backpacking trips. In the summer, this pack has more than enough room for all my gear and plus some. In the winter, this pack easily holds all my extra winter gear. Great craftsmanship throughout. Like a monster, this pack loves to gobble up your gear. December 5, 2012
Rated 5 out of 5 by Great bag for heavy loads I bought this bag to use for hiking and hunting. I have loaded this pack up with 70+ pounds on multiple occasions and it carries the load very well. The removable stay at the bottom of the pack is great for the really heavy loads. The load lifters are functional and takes the weight off of my shoulders like they are suppose to. I am very happy with this purchase! July 27, 2012
