I got this for Christmas and just used it for a week in NYC-- it knocked down the wind well and I was warm with the shell, a mid-weight Gap poly-fill jacket and two layers of shirts underneath. The low Tuesday was 13F and it was 1F with the wind, but I stayed warm during a full day of walking the city. It also kept me dry during the snow Thursday AM while we were outside the Today show.
I love the pockets and the length of the jacket. I am 5' 10'' 190lbs and the large covers down to my butt in the back and the sleeves extend past my wrists just enough that they don't pull off gloves when my arms are up.
