Great Jacket

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

This is a preliminary review. I've owned enough products like this that I can comment on just about everything except durability.

Design and workmanship are first rate. It's a unique jacket. Most fully-baffled ones are in a higher weight class, and are much bulkier as a result. This is a mid-weight jacket with baffles, so it gets its warmth largely from efficiency (lack of cold spots). Smart. It's probably more expensive than just throwing more down at a quilted design, but we get a more trim jacket that looks and feels better than the competition.

It should be equally happy as a belay jacket, a winter mountaineering camp jacket, and an around town jacket. The synthetic insulation in the sweatiest places suggests use with a pack, and supports use as an expedition jacket—I can't comment on this from personal experience.

I'll use it primarily around town, occasionally as a belay jacket (when too cold for my synthetic jacket), and maybe as a camp jacket for winter mountaineering.

For around town, it might be improved by a slightly heavier face fabric (the city is harder on my clothes than the mountains) and by slightly less fluorescent orange trim (YMMV ...).

Some nits to pick: the cord pulls and locks, while stylish and sleek in Mammut's impeccable Swiss fashion, are hard to manipulate with gloves on. I think bigger cord locks, especially, would be helpful. Some kind of gusset under the arms would allow for better arm mobility, although this would matter mostly if you were climbing in the jacket, which is unlikely. The double zipper, which is important for a belay jacket, in this case is a bit hard to get started. I suspect this will annoy me whenever I have to zip up with gloves or cold hands.

I'm tall and thin, and so greatly appreciate Mammut's trimmer fit. Usually I need to buy fridge-sized jackets just to get the arms long enough.

Hey, thanks for the info! Would you mind telling me how tall you are, sleeve length and what size you got? THANKS!!

I'm 6'5" and I ordered the XL but it's not quite as slim fitting as I hoped in that size and I'm wondering if I can get away with a Large.

Responded on

I'm 6'3" and have a plus 6" ape index. I don't actually find the jacket slim ... it's just slimmer than most down jackets in the same size. For myself I think the large would be too short in the arms, but would have a nice, lean, technical fit. How it would be on you really depends on your arms. Unfortunately I couldn't find details on sizing on the mammut site. Maybe you could send your measurements to their customer service people? They answered one of my questions the same day.

Responded on

I'm 5,10 and I have a medium... I'm a climber and a swimmer and as I'm concerne, the fit for the shoulder is awesome! It looks more slimmer then those in other brand.

A size too big

  • Familiarity: I returned this product before using it
  • Fit: Runs large

bought many Mammut pieces previously... Although this is the first down jacket I've purchased... The sizing is inconsistent with the previous items I've purchased and is running much larger.

I'm exchanging for one size down and will update my review.

Unanswered Question

Hey, I'm 6'5" 220, with a 48 chest and a 34 inch waist (athletic build). For this reason, Norrona is my favorite brand because their stuff fits awesome. That said, I wear a norrona XL and was wondering how the fit of these Mammut Jackets compares. Thanks in advance.

Love this jacket

Love this jacket

It repels all liquids

How is the sizing? Does it fit big? long in the sleeves?

Responded on

It fits better than any other down jacket I have owned, it has a slim cut. It is not bulky yet super warm. The sleeves are long, there is no velcro "cinch" or closure on the sleeves, just the built in hand gaiters. This jacket really is worth every cent!

Excellent service

  • Familiarity: I gave it as a gift
  • Fit: True to size

Thanks to the people in live chat. I've got a quick answer in a return and then in some questions about the paying method. I'll be happy to buy again with you.

My favorite jacket

  • Familiarity: I've used it several times
  • Fit: True to size

This is an expensive down jacket, and given the thickness of it it does not seem to warrant it. However, it has every nice feature you could possibly want (at least that I've ever griped about with other jackets). I happily got it on sale during black Friday in preparation to my move to Maine for the winter.

I've only used it for a couple months now, but I don't think I could have asked for a better jacket. What it lacks in thickness it more than makes up for by covering you completely. It sits just bellow my buttocks, has nice hand gaiters, a hood that is spacious enough for a helmet yet not vacuous around a bare head, the collar can easily cover up to your nose and potentially higher, and it fits my general athletic build wonderfully. The double chamber construction definitely adds warmth. In all, this is a much warmer jacket than my much thicker Patagonia Fitz Roy.

This jacket has kept me quite warm well down to zero F. Definitely warm enough on its own to take you down to 20 F and if you add more layers below (I chose fleece generally), it can go much colder. An extra shell on top of this would be unnecessary except in the wettest and windiest conditions, it is wind and water resistant to the standard of a soft shell.

I can't imagine myself paying full price for this, but for someone looking for something between a parka and sweater, this would be the jacket for you.

My only gripe is the color. I bought the orange and it is about as bright a color as you can imagine on this fabric, search and rescue retro-reflective comes to mind. In hindsight I would have gotten the blue. The black would draw the least attention, but I do enjoy colors in my clothing.

I have an ambler hooded down jacket medium...

I have an ambler hooded down jacket medium size. That is slightly larger for my body. I think ambler hooded jacket is little bit larger than other mammut jackets. Can you compare the size with ambler hooded down jacket and eigerjoch down jacket?

Responded on

Disclaimer: I don't own either of these jackets, however from what I know about specific use of these jackets and how different kinds of products are cut I would suggest the following. The Ambler jacket (that you mentioned seems big) is a 'big' puffy. It's meant to wear while belaying, hanging around camp, and generally will be worn on top of all other layers, including a shell. This jacket (the Eigerjoch) is a bit slimmer, and seems to be cut more athletically, it is made for layering under a shell as an insulation layer if needed, and generally has a much different purpose then the ambler. I would suggest that this jacket will fit more similarly to how you would expect a medium to fit

Surprisingly Warm!!

  • Familiarity: I've used it several times
  • Fit: True to size

This jacket is awesome! At first I thought I ordered a windbreaker. I didn't think a jacket this thin could be so warm. The Pertex Endurance shell fabric holds up in extremely cold weather. When it's -10 and windy, this is my go-to jacket (with a sweater underneath). Also, has a stylish look to it as opposed to a huge puffy jacket. Hood is awesome! When I walk to work in sub zero temperatures, I throw on the hood and I'm good to go!

Responded on

Are you saying this 800 fill/250gram feathers/710 total gram down parka wears and looks like a windbreaker? Can you post up a picture of you wearing it? I need to see this.
Thanks.

Awesome!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I love this jacket, by far my favorite down, i have mountain hardwear and patagonia, its perfect for winter bouldering in Bishop between climbs. Im so stoked its winter again so i can start wearing this again
Im 5-10 160 athletic build and medium fits perfect

only con is zipper can be iffy to get started but honestly not a big deal

I am not sure of my size in this jacket....

I am not sure of my size in this jacket. The large seems awfully big, but I usually buy large in most Mammut jacktets and shirts. The medium is a little snug at the bottom, but for skiing it seems like a much better fit. Any recommendations?

Responded on

I would have to know your measurements to say for sure, but I am in between on Mammut sizes as well. I am 6'0" and wear Mammut down in a medium and their shells in a large. I would recommend going with a medium on this particular jacket as long as it is giving you enough room in arms and shoulders.

would it be appropriate to wear this under the Nordwant Jacket (shell)?

Yes this would be a very good compliment to the Nordand, Meron, or Felsturm.

GREAT DOWN JACKET

  • Gender: Male
  • Familiarity: I've used it several times

I lOVE IT SO MUCH ! GREAT !

How much down and how much synthetic...

How much down and how much synthetic isolation material does this jacket contain? The jacket in the picture looks a bit understuffed. Is the warmth of this jacket comparable to the MH Nilas jacket or the RAB Neutrino Plus?

Responded on

From what I read and heard as well as seen on the demo video this Eigerjoch is 800 fill but varies the loftiness over the different regions of the jacket. Where as the Endurance Plus or a classic down/synthetic coat will have even distribution the Eigerjoch varies it so where you need warmth the most will have more loft and where you don't need loft/warmth at all will have little to zero fill loft.

In theory this makes it LESS warm than the other coats BUT MORE USEFUL when you are doing active outdoors stuff in cold weather.

Responded on

800 Fill is the measure of quality of the feathers not the weight. You are looking for an answer in grams and not Fill. For example the lighter Rab Neutrino Endurance is a 625 gram jacket that has 225 grams of feathers while the heavier bulkier Rab Neutrino Plus is a 760 gram jacket that has 275 grams of feathers. Because this Eigerjoch is a 710 gram total weight jacket with the same 800 fill quality feathers as the Rab jackets it should have a fill weight of around 250 grams or somewhere between 225 and 275. So it would be comparable to the Rab Endurance Plus for warmth but feels lighter on your back.
