Description

Breathe.

Fast-paced climbs call for the Mammut Felsturm Half-Zip Jacket. Instead of smothering you with stuffy, heavy fabric, the Felsturm's Gore-Tex Active Shell construction keeps things light and breathable.

  • Gore-Tex Active Shell is super light, it resists water and wind, and it breathes like a champ so the inside of your jacket won't become a sweat-lodge during your expeditions
  • Three-point hood adjustment system use a horizontal and vertical drawstring for a snug fit
  • Reinforced hood shield stands up to strong wind gusts
  • Frontreach sleeves for comfort while you climb or pole-plant
  • New zipper design attaches the spiral directly to the outer material, which saves weight, increases flexibility and compressibility, and eases zipper operation
  • Packable construction also makes the Felsturm ideal as an emergency jacket

A nice minimalist jacket.

  • Gender: Male

A nice minimalist jacket. It uses Gore Active Shell and has a mix of excellent and poorly designed features that lead us to prefer other lightweight shells. The Felsturm, for example, runs a bit short in the arms and the torso, has pit zips (a feature that we believe is unnecessary on a Gore Active Shell jacket), and lacks a drawcord adjustment at the waist.

Great Looking/Functional but not perfect

This is a beautiful jacket, very lightweight and finely constructed. Unfortunately I had to return my jacket due to sizing issues. I'm 6-feet tall and 180 pounds. The large was too small and tight. The sleeves were too short; if I extended my arms upwards, the sleeves would expose 2-3 inches of my arm. The chest/torso area is too tight; you could only layer with a t-shirt or thin-fleece (nothing thicker). The other disappointment is no drawstring in the hem. Too bad b/c it's a great looking and functional jacket.

Well constructed, but some issues.

The jacket is stunning in appearance, and although I did not wear it outside I have another GT active shell garment and I can say that it definitely breathes better than Pro Shell. The helmet issue is a problem, but for me the half-zip is a more serious problem. Of course I knew it when I purchased it, but half-zip jackets for full-on mountaineering do present problems in terms of taking them on and off, but more importantly, they do not vent as well as full zips. It is a very well constructed jacket, and if you are not using a hood, and are comfortable with a half-zip, then this is otherwise an excellent product.

Sizing

Hey,

I'm 5'11 and about 155 lbs. Pretty long back and i've always had trouble with jackets being too short. Should I go for Medium or Small?

Responded on

I am a girl with the exact same height and weight as you and went with the large in this one and don't regret it, because i use layers underneath. It runs kind of small for a men's jacket, it hits me in the hip area and does not cover my butt. As far as the looks goes, it is awesome...one of my favorite shells i have ever bought and orange is really bright and beautiful. So is blue. Hope this helps.
Medium might work for you, small will definitely be too small. Hope this helps.

weighs next to nothing

Love this piece. read the reviews but not sure what all the talk about the style not fitting over a helmet is about. I was in Europe in Feb and tried this on in a shop in Zurich and fit over a in hold climbing helmet. Bought it and it works with my Petzl Meteor just fine. Maybe doesn't come all the way over the very front but certainly will keep you dry. the talk of this being a "yuppy" style jacket like a TNF piece is absurd. This is the most technical style I's seen. Stuffs into a stuff sack the size of an orange, has the most trick zippers I've ever seen and don't think anyone else use these. The Active Goretex breaths better than my pro shell and is just bomber waterproof. This will live in my climbing and ski pack for sure. I think it wieghs in at about 10oz's

Sweet non technical jacket...

Hood blows. Small even on just a bare head no helmet. Anyone whom suggest a hood other than a R1 hoody be worn under a helmet is just retarded. Taking my helmet off every time my partner is outa eye sight to remove my hood and put it back on? I don't think so!

None the less this sits at the bottom of my gear bag as it looks that nice. If Mammut keeps building pieces like this they are gonna turn into TNF real quick and just be yuppy gear. Thank god that is not the case as Mammut made many other items in the 150 anniversary line that are proper functional climbing gear and not just a pretty clothes.

Not a technical jacket.

Technical jackets normally have helmet compatible hoods and this coat does not. Otherwise it is sweet. Cut a bit bulky through the torso so it bunches a bit. Suck a sweet color though it would be easy to see by if i just wanted a yuppy coat.

Well other than the non euro cut that is. It's orange like a orange and sweet sweet sweet. " IN REGARD TO LOOKS ONLY"

Responded on

A helmet compatible hood is not a sure sign of a technical jacket. Not all jackets are designed to be worn over helmets. After all, it's your head that needs to stay dry, not your helmet. Did you think about wearing it under your helmet perhaps? I'm pretty sure that's the idea... When I'm climbing, I always prefer a hood that fits under my helmet, and I'm sure there're plenty of others that agree, hence this jacket.

Responded on

They never make quarterzip technical shells. This is a great jacket for alpine climbing and hiking. most climbing jackets design the hood for under the helmet. Teh sleeve articulation is really good and the cut doesn't seem bulky when layering. Thanks for your opinion though.

Responded on

I just love taking my hood on and off so i can hear my partner. Even better is it getting all full of precip and then putting it back on.

;)

Will the hood fit over climbing helmets?...

Will the hood fit over climbing helmets? ( I've seen mixed reports from owners).

Responded on

You may be able to squeeze a smaller helm into the hood, but it is not truly helmet compatible. When you force a helmet into a non-compatible hood, you generally limit your range of motion, which can be dangerous depending on the activity or situation.

Responded on

I can fit my BD Half Dome (size M/L) under the Felsturm (size M)... however, with the zipper pulled up all the way, the range of movement left and right is restricted. (Up and down is fine.) Unzipped 3 inches from the top, which exposes my chin, but nothing else, there is unrestricted movement in all directions.

packs the size of a large Orange

This Felstrum Jacket is so lite and stuff's into the included stuff sack, which I could not beleive it would fit in such a small space, but it did. The zippers they use are super trick and work very smoothly for a waterproof zipper. Never seen one like it. The Active shell breathes better than any other shell I've used. Wore it on Longs Peak the other day hiking the whole time with a pack and moving fast up the keyhole route. Never took it off. Super windy on top and zipped it up tight and was windproof. Didn't get more than a sprinkle so can't attest for the waterproofness but its Gore tex so I'm sure its bomber. Money well spent will use this thing plenty I'm sure. Fits great and just so lite it feels like you are not wearing a shell.

Responded on

Is it still pretty warm despite the lightness of it?
Also, is it something thats best suited for aerobic activities or will it keep you warm just walking around in cold weather?

Thanks

Responded on

The Active shell is windproof so you will not feel the wind coming through. But the shell is made to be waterproof and very breathable. It weighs 10.2 OZ and is pretty thin. Like most shells its not going to insulate. Less convective heat loss. Great for high aerobic stuff like ski touring or running, also works great alpine climbing and skiing. Just layer up under it and its super versatile.

Responded on

Just returned from a rainy (low) and snowy (high) trip to Rainier. This was a great layer to have -- i wore it with a light l/s wool base layer, and most of the time, that was a great combination. The Felsturm really does move the moisture away; I think this is the best gore-tex layer for high output (i.e. sweaty) conditions that I've every used. On the other hand, I've decided I don't love the 3/4 zip. It looks slick, but in the end, I don't seen any advantage vs a full zip (please don't say weight), and it is a little harder to deal with when adjusting layers.

What the hell!!!

This jacket is sweet, Mammut really nailed it with this one. However with that said mine is getting returned.

Mammut claim this jacket is designed with climbing in mind the half zip and low bulk and wearing a harness blah blah blah. That is all good and fine but most people that climb also wear a helmet. They also claim this jacket is helmet compatible and "IT IS NOT HELMET COMPATIBLE AT ALL" !!

I can Barely get the hood over a Petzel Meteor and then it is almost impossible to zipper all the way up not to mention turn my head. Its like Mammut cut the hood 2' short of working with a helmet. With the sweet delicate zipper it is just crying to bust open!!

Now with a helmet compatible hood this jacket would be sweet and i would not be returning it.

The Orange color is one of the nicest orange color coats i have ever seen and i want to keep it on looks alone. However it is cut to be worn over layers and has a kinda balloon bulky mid section fit. The shoulders and arms are awesome!! The fabric is sweet and i can just tell it would breath really really well. I would even go as far as to say i could imagine wearing it on crazy cold winter days for running.

It's really just a shame as if the hood was helmet compatible this jacket would rock as a climbing shell. As a around town coat the balloon mid section is a bit weird. I cant really see this coat being used for anything other than climbing with the half zipp and all. I mean you could use it for hiking and general mountaineering but i would much prefer a full zipp in that case if i was not in a harness.

If you don't rock a helmet get it. If you do pass and get the Gipfelgrat jacket as that is one sweet jacket made for alpine climbing!!

How does a company like Mammut miss something like this in the design process? They must rock some tiny helmets?

Responded on

I read another review elsewhere that said the arms on this Felstrum were not articulated and rode up with the jacket so it was impossible to use it for climbing or paddling because the minute your arms go up the jacket rides and bunches up in the torso. I also just returned the Mammut Advanced Jacket because of the same defect.
Did you find this to be true?
BTW - that reviewer also complained about the hood issue.

Where is this jacket made?

The Extreme Mammut line used to be made in Germany but now I think they are either made in Latvia, Romania or Turkey. I own quite a few upscale Mammut Jackets and those places are where they are usually made. One jacket that I had back in 2004, the Logan/Lhotse Extreme, was actually Made in Switzerland but that jacket cost $700 USD back then and is no longer made or sold. Mammut sells some low end items like t-shirts and belts that are Made in China or Vietnam but I've never seen their Jackets and other high end pricey outdoor gear come with Made in China on the label. Even their wool and acrylic Beanies (with the exception of the fleece logo beanie) that I own are all Made in Germany (see picture).

Laughing man, There is nothing in the way of taped waterproof breathable made in Europe and has not been for some time. Mammut still sews quite a bit of their fleece, cotton and softshells all over Europe. Beanies still made in Germany is great. But sewing a beanie is not super technical to make so they can pull it off. The Extreme Logan and the others were not made in Europe either (not in at least the past 5 or 6 years) They were just made of the beefiest most expensive fabrics in the Gore-tex catalog and that's why they were so expensive. Pretty much all hardshell Goretex and other taped outerwear is made in China, I think ArcTeryx still sews a bit in Canada but beyond that no major manufacturer is doing it. If you check out the quality of this new Eiger Collection you will be impressed. It's as good as it gets. There is quite a bit of technology in the fabrics and zippers. Fit is great to. There are no factories set up any where else that can do this type of manufacturing, welding and sewing for a price that is at all commercially viable. Sad to say, but it is true.
