Rated 4.7 out of 5 by 10 reviewers.
Rated 5 out of 5 by Awesome Pack When looking at this pack it was rather difficult to find any good reviews so I was a bit skeptical before purchasing it. My biggest recommendation is this pack is pretty light and when compared to the 50L pack its virtually the same weight. The cool thing about this pack is you have 70L but can definitely pack it down smaller if you need. You can pull the compression straps tight as well as remove the top pocket shrinking the pack. While being the same weight as the 50L I don't see why you would steer towards the smaller 50L pack. This is honestly a great all around pack. Its water resistance is great in the rain/snow and its really nice to not have to worry about putting your stuff in bags all the time. Id say the only cons of this pack are not having smaller external pockets, no waterbottle holder or dedicated Camelback pocket (you can make due with using the back pocket underneath the crampon slot).

Rated 4 out of 5 by Good Simple Pack Have had it not quite a year now, but it has served very well. My son took it to Philmont where he experienced heavy rain. No complaints about keeping things dry. Haven't had it long enough to say how it will stand up over time. It is lightweight, yet packs enough to keep you going for a long week. November 10, 2015
Rated 5 out of 5 by Sturdy backpack Very versatile and reliable. Great for any long hike or challenging ascent. August 15, 2015
Rated 4 out of 5 by Great winter pack Ive used this pack a couple of times. Overall very happy with it. This is definitely a bag for lighter loads as the suspension system, especially the belt seems to be build more for securing the pack to the wearer's body vice a primary load-bearing function. My opinion is that the bag is a good winter bag where you need volume but won't be carrying a great deal of weight. I am 5'10, 190# with an athletic build and ordered a M/L size. Unless there is something Im missing, the pack is not adjustable size-wise and I find that it rides a little low on my backside (not in the small of my back/upper buttox as I prefer). In other words it feels a bit big for my size. May 27, 2015
Rated 5 out of 5 by A Monster Pack I have the previous version of this pack and I am writing after what I consider ample time to put this gear to the test. I am an avid back-packer and outdoorsman and have strained every fiber of this bag only to have it Overcome my abuse and wait patiently for the next trip. Unlike the other reviews I have read, I really load this pack down. I have three kids (who all backpack with me) but I tend to carry more of the weight! Normally my SouthCol weighs in at 65 pounds and I have put literally hundreds of miles and weeks on this pack in the outdoors... from Yosemite, CA to Mount Rogers, Virginia. I have attached several external pouches to the pack for medical(Tourniquet to band-aids), Signal(pen flares/mirror/fire), Navigation(GPS/Maps/Compass) and protection(Glock19 & Benchmade). This pack handles it all, trust me. I have snowshoed for two weeks and had dry gear in Nevada, walked thru the thunderstorms in North Carolina, and trekked thru Yemen... tested and proved. Enjoy this pack people....for a decade or two...it's that tough. Caveat, I take extremely good care of my gear pre-trip, during the trip, and post-trip which makes it last. March 29, 2015
Rated 5 out of 5 by Fantastic winter bag!!! I was quite excited to try this bag out once I ordered it and it performed as I expected, superbly! As with all my experience with Mountain Hardwear gear I was not surprised. I recently used it on a quick winter excursion with my six year old daughter (had to carry her gear as well as mine). I was surprised with the comfort of the bag and although I was only carrying 35 lbs. it felt very agile and supported the load well. I love the fact it is 70L, as winter equipment tends to be slightly bulkier and not necessarily heavier. This bag seems optimal for the average 45 lbs. winter bag. The OutDry is an awesome aspect of the bag, not having to worry about anything inside getting wet or carrying a frozen soaked bag is nice. The material of the bag is durable and I look forward to having this bag for many seasons to come. I was very pleased with the functionality of the gear placement and its compression system, it is noticed a lot of thought went into the design. I have a few more trips planned this season so I will get more extensive use of the bag and update my review accordingly. Overall, so far I am very pleased and believe it is well worth its weight.

Rated 5 out of 5 by Versatile and lightweight, 2 packs in 1 This is by far the best backpack I ever owned. Works both for heavy loads - although not too comfortable when I had a 26 kg, but manageable - as well as a summit day pack, since it can be reduced to a pretty small size. Material is super durable and truly water proof. Overall, a super versatile backpack, that can be used in many different occasions, but to an alpine climber in the big mountains, it serves a double purpose (carrying loads + summit push) with the benefit of being super lightweight, thanks to no unnecessary thrills, and just the right amount of pockets and straps.

Rated 5 out of 5 by Just right Just arrived home after a weekend backpacking trip, 30 miles or so, with this pack. It is the first I have purchased of its kind, and I can say that it was great. At first I was a bit confused as to how to pack and cinch it down properly, but I soon found every chord, pull, buckle and fastener in natural positions that my hands easily found. The weight distribution was great and honestly felt "light" on my back and hips. You can really cinch the pack tight against your body so you don't get that swaying pack motion on the trail. The 70 seemed like it was going to be gigantic at first (and it is!), but it is collapsable enough that you feel like you are wearing something much smaller. Thank you designers! May 25, 2014
Rated 5 out of 5 by South Col 70 OutDry I have had used this pack for a total of about eight days in winter conditions and I love it!! it is light enough for its size and very user friendly. the crampon pocket is outstanding. There is no reason to use a crampon bag with this pack. snowshoes and ski poles as well as ice axes are easily attached and removed. This is the most comfortable pack of this type that i have ever worn. I believe this is the best pack in its category available. March 2, 2014
Rated 4 out of 5 by first impressions I ordered this when it first became available so I have had a few weeks to try it out. Mother nature sent plenty of rain and wet snow this way, so I am pleased to say the Outdry tech works as advertised. Also working as advertised is the large front pocket that keeps its volume even when the main compartment is stuffed. That and the crampon pocket will be much more useful to me than the daisy chain that occupied this space on the previous version. Also gone is the small inner lid and hydration sleeve, neither of which I will miss. The ice axe attachment is a neat idea, but even with the loop fully loosened, getting the loop around the axe head and the pick in the sleeve was a very tight squeeze. With some tools it might be necessary to ignore sleeve and use the loop in the traditional way. Or maybe I was just doing it wrong. It would be nice if MH included diagrams to illustrate the intended use of various features. The zippers on the pack were a little sticky but I expect they will loosen up with use. The load lifters now have handy thumb loops to make them easier to tighten with gloves. One change that is not for the better is that it is offered in only two sizes, S/M and M/L, not S, M, and L like with the previous version. Side by side with my old size M South Col 70, the pack size of the S/M appears identical but with a significantly smaller hip belt. My normal pant size is 32, and it fits, but without any length to spare, especially if I am dressed for the cold. Nevertheless it still supports 40-50 lb. loads ok and with decent comfort for a pack where the design priority is keeping things light. Overall my first impression is that this is an excellent pack, but I am deducting a star from the rating due to the more limited size options. Some people sized to a medium in the previous version might be out of luck with this one. February 15, 2014
