It’s called the Ultimate for good reason.

With unparalleled wind protection and stretchy weather resistance, it’s no wonder Mammut Men’s Ultimate Hooded Softshell Jacket got its name. This versatile shell fends off all but the worst storms while remaining highly breathable, and its Gore Windstopper shell fabric makes it ideal for exposed alpine pursuits. Underarm zips dump heat on long ridge slogs or skin tracks, and cuff thumb loops provide extra hand protection.

Great Jacket

This is a beautiful piece of clothing that has the features I am looking for plus comes in highly visible and attractive colors this year including cayenne red and curry yellow. The cut of the jacket, longer in back, shorter in the front is great for a harness and the hood is helmet friendly without being cavernous so that your head gets lost without a helmet. The side zips extend all the way from inside the biceps of the sleeve arm down to the hem of the garment making it highly ventable as well as highly breatheable. The medium size fits me well @ 150 pounds and 32" arms. Overall a great performing garment that is suitable for ice climbing, back country skiing and looking good around town.

I love this jacket

This jacket is a great waterproof shell. It is advertised as water resistant, but it has definitely kept me dry in multiple hours of rain backpacking. Looks great, perfect athletic ergonomic fit, great materials, very light.

Great for alpine and ice

This is a great softshell for alpine and ice climbing. I love the long sleeves and athletic cut. The many options for ventilation makes it perfect for both the walk in and the climb itself. The woodbine is greener than pictured (even on a calibrated monitor) but actually I like the real colour better. The hood is just big enough to go over the helmet.

Hey does this have any sort of liner? Like microfleece or anything. How does it compare to TNF Kishtwar or the Marmot Kingpin in this regard? Thicker, thinner?


Responded on

No fleece liner - not sure how it compares though. Very light - nice jacket. The only item that is a little annoying is that the metal zippers on the inside are not protected and are cold on your arms if you don't have a shirt with long sleeves on.

Nice sytle - might do the job

The woodbine color I ordered is more green than it is the yellow my computer displays. The jacket's sleeves are a bit long and the zippers are cold against your arms on the interior. I ordered a large to accommodate for layers under it and give myself some room to move, but I am swimming in it. I am 5'10 / 180lbs.

I also noticed that the full zippers on the side tend to come unzipped rather easily with a little movement - this is not exactly a great design as you have to stop and re-zip them.

Overall, for the money, I think there are many better jackets out there but if the styling does it for you, you just found yourself a pretty lite duty softshell that is pretty stretchy.

Worth it.

This jacket (was called a hooded sweater when I bought it) is super primetime. I wear it as either an outer layer or a base layer in winter, with a shell over the top. It sheds wind and rain, and with a lifetime warranty, you can't go wrong. Everyday apparel, can be worn as a jacket or a sweater in my opinion.

durability issues

I love the design and fit of the Mammut Ultimate Hoody. I bought this jacket January of 2010 so I have given it a good run. This Mammut jacket replaced an Arc'teryx Gamma MX jacket that was great for 6 seasons. Every little thing wants to snag the extremely vulnerable soft shell material of this Mammut jacket(I never had a single snag on my arcteryx soft shell). I was willing to over look the snags until a slight snag that occurred February of 2010 has progressed to a hole that opens down to a white inner layer 9 months later.
I am not impressed with the jacket, and if I could give it back I would. That jacket got two more snags yesterday after brushing up against a wood table. The jacket still looks good, but I am always feeling overly concerned about it. My Mammut Gore-tex Proshell is great.

I love this jacket. I looked for a windproof softshell that had big pit zips forever. Finally I found this thing. I wanted something that I could do intense aerobic activity with without removing when overheated. This is it!! You can zip up from the waist on the underarms or the middle zipper as well as down from the chest or the elbows. I started biking in 38 degrees and felt good with the ind proofness and then finished 45 minutes later with pit zips half down and was rocking comfortable. The comfort is great!

Ultimate Breath-Ability

Have had this for two years now and it's one of my favorite jackets to use. I am always overheating when hiking and the ventilation on this is amazing. The pit zips run from the elbow down the entire side of the jacket, and can be undone to let the jacket drape like a poncho. The zipper can be zipped open from the bottom, allowing more venting options if you do not want to take the jacket off as well(pit zips also do this). I'm 6'1" 180 lbs and the large fits great. It is a more athletic cut, but I can fit a Montbell Ultralight Thermawrap Parka underneath(though it does make you look fat). The hood is not helmet compatible. The Windstopper material makes it nice and stretchy, fending off wind like a champ. Light rain and dry snow are no issue either. I do not recommend this for prolonged downpours or wet snow/rain as it is not waterproof and the outer material does catch wet snow pretty well. After 4 hours of snowshoeing in 34 F and snowing my shoulders were soaked. I do not hold this against the jacket though, as I was trying to see what it could take. If you are in a dry climate or need a jacket for sunny days, this is it. I do not see myself buying a new softshell any time soon.

love the full pit zips

great jacket for its intended use. I use it as a spring ski jacket, and it works great. The best feature of this jacket is the huge underarm vent zips. They can actually be unzipped all the way, so the jacket can me more like a poncho.
The fabric is smooth, and can be prone to picks... so this is not the jacket to take crack climbing... The hood fits snugly, so it works under a helmet.

One soft shell that does it all

If you only want to get one soft shell this is the one you should get. With Gore Windstopper this jacket fends off wind and light rain like a champ. and with huge side zips for ventilation it is easy to dump heat after a long session of skinning or charging on the mountain bike. I have nothing bad to say about this jacket. stop hesitating and buy one.

Great softshell jacket

Noble fabrics with exquisite smoothness to touch. Very light and supple, and a real wind stopper. Some may like it hot but side zipps are big plus ! As are thumb loops when you need some more protection. It has an athletic cut but does not constrict you. It gives you plenty of room for movement and activity.Beware: this softshell jacket has no lining. It is not meant to increase your body temperature. It is supposed to prevent it being blown away !Berny Blue is nice colour but Black is Beautiful !Great softshell jacket !

Wonderful Jacket

Been really impressed with this jacket and the other Mammut stuff I've bought. Thus is a really light Windstopper style. It seems to breathe much better than the Mtn Hardware Windstopper softshell I'm relaceing. The pits zips open fromt he bottom hem of the coat all the way to the elbow for amazing venting. Fit is perfect and seems true to size.

How does this compare for water-resistance and wind-resistance to the Arc'teryx Gamma MX Hoody? Which is the most breathable?

Best Answer Responded on

The Gamma MX Hoody uses Powershield instead of Windstopper, so it is only wind-resistant instead of windproof like this jacket is. The tradeoff is that the Powershield is more breathable. The advertising for the Gamma MX claims that it blocks >90% of the wind - I'll let you be the judge. As for water resistance, it's hard to say. Neither jacket is inherently waterproof, so you are relying on the DWR coating. I know for a fact that the Gamma MX is pretty impressive in light rain, but I wouldn't want to rely on it for prolonged showers or a downpour.

Responded on

The windstopper fabric doesn't breathe very well. However, the design of this jacket includes full side zips with double zippers and a front zip with double zippers. There are many ways to vent the jacket to prevent overheating. I haven't found breathability to be an issue yet.

Responded on

I would add that the Gamma MX is a little more of a stand alone piece. it is warmer than the Ultimate and the hood is compatible with a helmet.That being said the Ultimate is a jacket that you will never have to take off. You can wear it without really wearing it due to he venting system and it is a bit more windproof and lighter.

Stretchy, tough, and fully windproof

This jacket delivers in everything it promises. The Windstopper fabric manages to be stretchy and fully windproof. Working as a zipline guide, I get exposed to a lot of wind and this keeps my core and arms warm and allows me to move freely for those high clips that make me stretch. It has an athletic cut with just enough room for me to fit 2 layers underneath. I am an athletic 5'10" 160lbs and everything on my Medium jacket fits perfectly. Possibly the greatest cut of the jacket is the hood. It fits perfectly (without a helmet) and can be zipped up to hit the front of your chin. It feels a bit weird at first, but it is designed to block all that wind from hitting your ears and neck. This is the best jacket I own.

Thanks for posting this review. You sound like you are about exactly the same size as me.

Do you mind posting your chest measurement, so I can compare? I'm thinking a medium will fit me perfectly as well!

super vented softshell

The side of this jkt zips open like one huge pit zip from the elbow down to the bottom hem. Perfect for touring, hiking , climbing. Open up the vents and cool off, zip it when you stop moving and keep the heat in. Works great and just a style piece that fits great. Softshell fabric feels light but still really tough
