Excellent all around
I’m 6’4” and 190lbs. Wear a 40xl blazer and 35” sleeves. Great jacket and fit. I find Mammut gear to fit much like Arcteryx in that it is ideal for tall and lean. Nice amount of warmth but breathable. Soft. Easy on and off. Great for layering. One of the best light fleece jackets I’ve ever owned. I see several reviews saying arms are too long, but they have thumb holes obviously designed to keep sleeves in place and reduce wind creep during runs or other athletic activity. All pics of this item show it with thumbs through the sleeve on the models.
Great but why itchy tags everywhere?!?
Love the jacket, but don't love Mammut's recent change from printed tags to sewing rough, itchy tags in the neck line that are impossible to separate out without damaging the stitching of the jacket. Same is true for several t-shirts I bought. At least put the tags on the waist line of the jacket/shirt and not the neck!

it’s fine but not for me
I like the jacket a lot.. I thought it would have pockets other than the chest one. The sleeves seem a bit long as well.. I returned it. Perhaps a slimmer person would like it.
Great midlayer!
I bought this because I wanted something with a full zipper that I can take off easily and we're under a coat also at the neck protection which I like from the cold wind.
Awesome Jacket
One of the best things about this jacket is the sleeve length. It does not come up short by the wrists, perfect for those of us with longer arms. Then with the thumb holes it works great with gloves, way less snow gets in. I have used this as a mid layer for snowboarding and I was able to wear a lighter jacket than normal. The fit is also spot on for sizing and I like the athletic cut of it. This jacket is also just a nice one to wear when out and about. It got a few compliments when I wore to work at ski resort.

Very versatile piece of technical wear.
I've owned a variety of mid layers from all the big name companies. This is by and far my favorite, it is warm and comfortable and most importantly regulates heat well. I was initially skeptical on the fit as the chest is proportionally small for the size but the stretchy material accommodates for that and makes for a flattering look. I am looking to buy more Mammut pieces as this one far exceeds my expectations.

Love the light midlayer and slim fit
This is perfect. It’s hard to find these light synthetic mid layers that have a slim fit that you can wear for anything. I saw a comment that the sleeves are long, they have thumb holes so the come out to the palm.
Great product but poor stitching
Fits well for technical endeavors but the flatlock seam stitching on the wrist is unraveling on the second wear The color and fit are great as is the function and design. It breathes very well and the thumb loops are excellent but the stitching is poor. I can’t recommend due to this. I am going to have to warranty or try to sew it myself which is unacceptable after only wearing twice.

Arms are VERY long
Mammut gear is usually well made, and this is no exception, EXCEPT the arms are CRAZY long for some reason. I am 6'0", 190 lbs, and wear a 16.5/34 dress shirt, and these sleeves are at least 37". Really odd. Returning ASAP
A nice mid layer
A light, stretchable mid layer that can fit over or under most set ups. Very streamlined with only one chest pocket, most likely done to keep weight down and as backpack hip straps would have blocked access to other pockets. Versatile and suited for high aerobic exercise.
