Direttissima™ 50 OutDry® Backpack is rated 4.2 out of 5 by 13.
Rated 5 out of 5 by from I have put this pack to the test. I have been running this pack through its paces over the last 6 months, between training in the Cairngorms for peak bagging in the alps, or recently the months of lugging water up and down stairs preparing for an expedition in the Himalayas. The waterproofing technology of this bag is fantastic, although you sacrifice the ability to access the bag from anywhere but the top. I also noticed that when not completely full, there is a little play left in the top pouch. Aesthetically this is a very sharp looking bag, and the crampon pouch in the back with water vents is a nice touch. This is also a very comfortable bag. I have routinely been training with, or carrying over 40lbs and this bag lets you disperse that weight well with good support from the hip pad. For longer expeditions I will be upgrading to a the same line of pack, with a larger capacity, i.e. the 70L.

Rated 5 out of 5 by from My new favorite mixed climbing pack I have a hard time finding back packs that fit me and my needs, I am tall and slender and this pack fits me perfectly. It is form fitting for long hauls into the ice and distributes the load with a good balance also snuggs down tight when you start climbing. The waist band is thin enough that it doesn't interfere with my harness and there arent any extra straps or pouches that could catch on ice screws or other climbing equipment. I climbed earlier this year with a competitors pack and it rained half way through the trip soaking everything inside so I am looking forward to the waterproofing on this pack for future trips.

Rated 1 out of 5 by from Least durable pack I've ever owned. I've used this pack only a handful of times, a couple hikes and once with skis. After one time with skis strapped to the sides, the skis cut into the side wall enough to make the "outdry" waterproof material, no longer waterproof. Also my skis when used with the pack were on the duller end. Also, while on my most recent hike through the narrows in Zion, I noticed the contents of my pack were oddly wet, the pack was never submerged, but had a lot of splashing. Lo and behold, there's already holes big enough to put fingers through in the bottom "rugged" material. There's more design issues that bug me, but construction and quality alone make this a don't buy.

Rated 5 out of 5 by from Bombproof pack I have been using this pack for the past couple years. It's my spring ski mountaineering pack. Everything about it is great. These are the things I like about it: simple design, top loader, super durable materials, robust ski carry loops, like the colors, and it fits me really well. I'm 6'0".

Rated 4 out of 5 by from Great Pack With A Few Caveats I've owned the Direttissima 50 for almost two years now, utilizing it as my go-to pack for general backpacking, canyoneering, and traveling. I work as a guide for an outdoor program through a state university and between professional and personal trips, I've put away a good 1000+ miles with it on the trail. Overall, the pack is pretty bomber. I live in Arizona and the brush and general backcountry in the Southwest can be pretty brutal. The Direttissima has handled sandstone, granite, and cacti with ease. The only tear to the pack resulted from the design of the pack itself, which I'll get to later. Overall, like most of the MHW product line, the pack is built to last. I generally gravitate towards a alpine style pack, as I generally don't see a need for additional pockets or superfluous features. The Direttissima provides all the features I like, save for some issues with the following: 1. The zipper flap on the top lid is kind of useless, as another reviewer pointed out. The shape of the lip continually places tension on the lip pocket, forcing the flap up and open. I would prefer to see a sealed zipper used, if the lid design isn't changed. 2. The lid becomes pointless if the pack isn't over filled. Even if the main compartment is filled level with the exterior white pocket, the lid attachments on the back panel fail to keep the lid from sliding down the front when cinched with the front buckles. If you're only hauling 30L or so of gear, the pack looks clunky and doesn't accommodate those smaller loads well. 3. The exterior zip pocket is appreciated, but I find the crampon sleeve to be poorly designed. I would prefer to see an exterior similar to the smaller Direttissima 35, (which I also own and love) as it cuts down on excessive compression straps and clutter. 3.5. Straps. Everywhere. I appreciate the customization that can be done to compress and compact the pack, but the compression straps are all excessively long. If MHW could better measure out a fully loaded pack with respect to strap length, they could cut down on the amount of webbing significantly. All of the strap slack can be organized with elastic stays or small tuck away pockets, but it's still annoying to manage. 4. The aluminum stay has begun to tear through the hip belt. This is the only damage the pack has experienced. The stay has somewhat sharp edges on the end, so I've had to place a rubber stopper on the lumbar end to prevent it from chewing further into the insert pocket of the hip belt. Mildly annoying, but again, I've used this pack pretty extensively and considering this is the only damage that's resulted, it's not a big deal. Really, it's only annoying, because it's from the pack damaging itself. 5. A hydration port like the one found in the Scrambler 30 would be nice. Overall, I find this pack to be good, borderline great. With some minor refinements, I think MHW could quickly update this pack to be great, if not amazing. However, if you can do so, if you can make do with the loss of space, I would recommend first purchasing the Direttissima 35 pack, as I think it's overall a better designed pack. Bottom Line: if you're looking for a bomber pack that can handle a variety of weather conditions and locations, I think you'll really enjoy the Direttissima 50. I would recommend it if you're needing a pack of this size.

Rated 3 out of 5 by from Great pack with a few design flaws I was lured into buying this pack by its best feature: 100% waterproofness. It's hipbelt also felt very comfy and fit just right for me. I like the quick attachments for ice axes that keep the picks covered/hidden the external pocket is nice but you can't access it without unclipping the top lid. Crampon pocket is ok but would prefer a larger more universal pocket here. The pack seems super durable. The back panel is pretty comfortable. Problem #1- the zipper flap on the top lid stays flipped up providing no water shedding protection. It's useless. Prblm#2- if the pack isn't filled beyond the expandable collar the top lid slides down and doesn't provide 100% coverage to shed rain away from the main compartment. Prblm#3 shoulder straps uncomfortable, slightly too firm. Felt like it was bruising my left trapezoid with 46lbs in the pack. Straps aren't independently adjustable where they attach to the pack to adjust for wider or asymmetrical shoulders. Left strap wanted to ride up my neck & right strap wanted to slide off my shoulder. Adjustment of sternum strap didn't help much. #4 would love to see at least 1 hip belt pocket here. Do you really need gear loops if you are wearing a climbing harness? Besides these gear loops are located so far back they're hard to access. #5 Would be nice to have stretchy side pockets for securing lower end of tent poles, pickets, snow wands, or a water bottle #6 no hydration port or designated hydration sleeve

Rated 3 out of 5 by from Good pack when stuffed full This is a very well made pack. The durability and waterproofing are great. The external skin/crampon pocket is awesome. With pack filled it carries great. When stripped down it feels a little clunky. The clam shell top does not sit well on top of the pack if it is not stuffed full, and the compression straps don't compress enough to really sinch down the pack with a light load.

Rated 5 out of 5 by from Great, Comfortable Pack I just took this pack on a three day canyoneering, packrafting, backpacking trip through a remote section of the Grand Canyon. It is the most comfortable pack I have ever used. It weighed about 42 lbs when fully loaded with all my gear: harness, helmet, 200' of rope, webbing, stove, paddles, packraft, life vest (outside), bivy, sleeping bag, filter, 3 liter bladder, food and water. It did get a small tear in the bottom, but that goes with the rugged nature of the sport.

Rated 4 out of 5 by from Great pack a few improvements would make it awesome I upgraded to this pack before our 125mi trek in Switzerland hiking the Haute trail. The three features I really appreciated - (1) detachable top, (2) crampon pouch and (3) water proof fabric. The feature I miss is having mesh pockets on the hip belt to hold energy bars and snacks and at least one side mesh water bottle pouch. Comfortable and adjustable - Overall great pack and I highly recommend it.

Rated 5 out of 5 by from Ordered this backpack for a teenage gal She will take it on her first trip into the Bob Marshall Wilderness Area this year. She loves the fit and style of the pack. The design is very intuitive for her so she has real comfort with the fit but also with how her equipment, clothing and food fits into the pack. Excellent equipment makes a world of difference, especially for a new person to the backpacking scene. Thanks Mountain Hardware for helping a young gal enjoy such a great trip!
