Comments about Mammut Areana Softshell Jacket for Women:

This jacket is very lightweight and does block the wind. However, the fit is tight across the chest, long and narrow and the sleeves are very long. I am 5'5" , 130 lbs, and had to get a large because the chest is cut so tight. I had to get the sleeves shortened as well.
I use the jacket over a fleece in the winter. I just wish it was cut with a better fit.
