Familiarity: I returned this product before using it
Fit: Runs small
I don't really want to give a star review, because it doesn't seem fair, I just want to comment on the fit. I liked the jacket from my short time with it, but the fit is a problem, I wish I could have kept it.
I bought one and it was too tight in the chest, and that is not normally I problem I encounter. I disagree with a reviewer below that this fits larger than Arc'teryx down pieces, at least the Thorium.
At least in the chest, mine was smaller than Arc'teryx's down pieces (Thorium), significantly smaller. I am 6'1", 220 lbs and the XL fit well everywhere except the chest seemed about 3 inches too small, it was binding, whereas the Arc'teryx piece fit fine. This isn't a problem I usually have. I like the length, the waist size, the arm length, the wrist size, the shoulder fit, but the chest was way too tight.
Edit: Comparing the sizing charts of Mammut and Arc'teryx, I see that, for a given size, Arc'teryx has the same waist but a bigger chest. For a any size, Arc'teryx has the chest being 7" bigger than the waist, whereas Mammut has the chest being only 4.5" bigger than the waist. Apparently the Swiss are small chested people.
Their size charts seem to be pretty similar to Arc'teryx's, except that the chest circumferences are about 3 inches smaller.
