Description

Built for guides or mountain masters, the BMG hauls all.

You have a lot of gear to haul over a great big mountain, and the beefy Mountain Hardwear BMG 105 Backpack prevents backbone-buckling on the third morning of your trek. For that, you can thank the Alpine Suspension and smart compression straps that transfer your heavy load from your shoulders to your hips and allow you to carry this extendable, guide-worthy pack over countless ridge lines.

  • Two hollow stays add the structure you need to carry 70-pound loads and can be removed for lighter alpine quests
  • Removable HardWave framesheet keeps the pack flat on your back for a comfortable and predictable carry over goat paths and crevasse crossings
  • A large, stowable front strap condenses the main compartment when you’re carrying a smaller, low-bulk load
  • Low-bulk FitLock waist belt redistributes the majority of the load to your powerhouse legs
  • The removable top lid features a rope strap for alpine climbing trips and utilizes glove-friendly compression straps to shrink the load on the go
  • FlapTop design means that the pack remains weather-resistant with or without the top lid attached
  • Pack extends to provide up to 625 cubic inches (10L) of extra space during expeditions
  • A front daisy chain, sleeping pad straps, and ice axe straps provide a variety of external carry options

Here's what others have to say...

Question about the sizing. I see a S/M and M/L size available, but I'm not quite sure where I'd fit. I wear a 34 inch waist on everyday wear, but I'm unsure if I need to account for all the layers I'll be wearing on a week-long alpine trip. Since the S/M and M/L sizes appear to sit right on the 34-35 inch waist, do I go for the big size or small size?

Responded on

CaptainMurphy,

I can relate to your sizing. I'm a 33" waist and went with the M/L and pleased with the fit. This allows for my layers to fit properly under the waist belt and the torso length is much better for my height of 6' with 21" torso. Talking with the Mountain Hardwear rep helped me out a bit when choosing the right size.

When you receive your pack save all the wrapping and leave the tags attached. Try it on with your layers, if it fits, bingo, if not return it for a proper size. BC has a great return policy on new return and exchange.

Meanwhile I hope you enjoy your upcoming week-long alpine trip!

Fit and waterproofness of the new OutDry

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

If you purchased a BMG OutDry backpack in 2013 or 2014 and it does not fit right, it might be that you got one of a shipment of these backpacks that has the stays reversed. See photo and comment under the South Col 70 backpack. This is easy to correct by simply taking out the stays and reversing them (actually one stay bent in the shape of a U). Mountain Hardwear corrected this but there may be some backpacks still in use with the stays reversed (My new BMG arrived with the stays reversed). If you are curious about how waterproof the OutDry fabric is, see the results of home tests under the South Col OutDry. The construction of the two backpacks is very similar and both were tested. The results are quite positive. Note: my rating is of the OutDry fabric (you cannot post here without giving a rating). I will wait until I have had more opportunity to test the BMG backpack before rating it. So far so good.

So for those of you who have noticed that S/M and M/L are not sizes in the size chart link... here you go. This is a snap of the hangtag on the bag I took today. Measure your torso and compare it to this.

Great rugged pack

  • Familiarity: I've used it several times

Just purchased this pack and it is built tough. Loaded it with 80 lbs+ and did some testing to deternine the durability of the shoulder straps, sternum strap, and general material being used, and found that it far surpasses any of the other popular name brand packs. I have no concern with straps breaking on a climb with this pack (a possible expedition ruiner if you are carrying a lot of weight). Not overly impressed with the hip belt and find that it sits funny and seems overly large, even for a large pack. I would still highly recommend this pack to anyone. Plenty of capacity, and despite what the previous review said, it does pack up fairly small (remember this is still a 100+ L pack) when carrying smaller loads.

Not Impressed

Purchased to use for ski-boat-mountaineering trip in Southeast Ak. After taking it on a 4 day trip I have to admit I'm not impressed. Pack seems to advertise as being a big pack that can be shrunk back into a small pack when not needed. All this seems to do is make a bad big pack, and a sloppy small pack. The stowable side compression straps have sloppy fittings which get tangled in the crampon pouch on the front of the pack. They also tend to slip. The crampon pouch is build into the pack so when you have your gear in the bag you really can't remove or stow crampons. This means when you hit the icy part of the glacier you have to pull 1/2 your gear out of the bag and keep it from sliding into nothingness so you can pull your crampons out and put them on, really bad design here. The bottom compression straps are too small to attach a tent or sleeping pad too. I like that the pack brain is removable but was annoyed with the lightweight compression strip deal. It doesn't stow when not in use, and tends to just flap around on your head. Lastly the bag is just kinda funky. I feel that I can stow as much gear in my 70L Gregory as I can in this 100+L bag.

On a positive note this bag can haul a 90Lb load up a glacier and still be pretty comfy. It is also far more economical than its competitors. I feel that M.H is close here, but needs to rethink a few aspects of the product.

Also Backcountry doesn't honor their free shipping to Alaska. Bummer here. Rei does honor their shipping deals.

Does anyone know if this pack has a method for adjusting shoulder strap height?

Responded on

Has anybody got a response to this question? I too would be interested before I decide to buy a new bag.

Jon, gilp-- The BMG 105 has fixed shoulder straps. Torso adjustment (i.e. moving shoulder straps up/down) is a great feature but it does add weight and increases possible failure points.

There are Mountain Hardwear packs with this feature - see Shaka/Lani series. However, the BMG (Big Mountain Guide) was purpose built for professional guides and opts for the lighter and longer term durability construction and multiple sizes still allow for a great fit.

Hi Chris,
Backcountry.com strives to keep as up-to-date of an inventory as possible with multiple selections of products/sizes to choose from. At this moment, we currently have small, medium, and large packs available. If we don't have an item available I would highly suggest checking once a week as the inventory can change quickly!

Big Massive GINORMOUS

This pack has served me well over the last 2 years. Has stood up to everything i have thrown at it.

The fit is great right out of the box. The hip belt takes a couple of miles to adjust to. (most packs i have used need a little breaking in)

I have had 70+ lbs in this pack and it carried well. I can fit my 4 season North Face tent along with a -30 sleeping bag, food for a week, Emergency gear, and all my clothing and gear for sub 0 degree weather.

The pack doubles great for hauling climbing gear during the summer and I find myself using it for shorter summer treks just for the ease of use and option to carry that extra bit of gear to make life more enjoyable on the trail.

The expandable top section compresses nicely for shorter trips.

And like mentioned the pack does have a hydration pouch. With a loop for clipping on compatible bladders.

And if you have not worked with Mountain Hardwear on warranties they are amazing. Sent in an old tent with broken poles and a destroyed rain fly and was given new poles and fly and all i payed was shipping.
Great company to work with and always amazing products.

Designed for Denali!

I used this pack for Denali as well as multiple winter climbs in Colorado and the Dacks. I tested both Osprey and Gregory. This pack out performed all others. If your pulling a sled (Pulk) this is also the pack for you. Pricey but worth every penny!

A concern I have with larger packs is the...

A concern I have with larger packs is the ability to look up while wearing a helmet- does this pack have a little "scooped" out section to help create space when you tip your head back? (or similar solution). For example the Gregory Palisade 80 is shaped slightly to allow this but not quite enough in my opinion. Any help appreciated, thanks!

Best Answer Responded on

Mountain hardwear does not have a "scooped section like that. The only packs that I've used that have an intentional section like that for being able to look up while wearing a helmet would be Osprey packs. And if you are gonna go with a pack this large(6400cu in), Id go with Osprey(or Gregory) anyways because they seem to have better packs when it comes to large capacity. Mountain hardwear is better with mid sized to small technical packs. Hope that answers your question.

I was wondering how well this pack compresses down when carrying a smaller load?
I will be using it as an all purpose mountaineering pack, but also for warmer rock climbing trips where I want to walk in with all my sleeping/camping gear plus a sizeable rack and rope and be able to dump the camping gear at a site and still be able to go cragging with this pack.
Also, not a necessity, but if it works I would also like to use this for days out ice climbing.

Responded on

It compresses down quite well. Also,I have used mine on day ice trips with no problems.

Responded on

alo. It compresses down well but if you want the most versatile pack in our line I would check out the South Col. It is a bit smaller at 70 L but is lightweight and compresses down amazingly well. I hope this info helps!

um, dont clasp the top to the bottom

ok, if you happen to be playing around with this bag, looking to compress it a bit, and you decide (why i dont know) to connect the clasp from the top portion to the clasp from the sleeping bag compartment, be preppared to bust out pliars to get it undone. if you do this on the climb, you better hope somone has a leatherman tool. otherwise, its legit.

Hydration Compatible: YES

Just wanted to point out that the "Hydration Compatible: No" listed on the Specs is incorrect as this monster does indeed have a bladder pocket, accessed by a horizontal zipper on the back above the shoulder straps, and has a bladder clip and double zipper pulls and zipper cover flap so you can exit the tube from either side (or anywhere in between).

Haven't used it yet but just a few notes:
The bottom compartment swallows a large Bear Vault cannister easily through the Big Mouth zipper with lots of room left over.
Zippered internally hanging flap-pocket {about 6" x 10", waterproof?} on the back (above the hydration pocket) with a key leash clip inside.

Responded on

I think you're referring to a different pack. The current BMG 105 Outdry doesn't have a hydration pocket, "big mouth" zipper or internal hanging pocket.
