Love, love, LOVE this jacket. At an athletic 5"5', 131 lbs, I generally average a size 6-8 in jackets and a 4 in pants. I sized up to a medium in order to facilitate layering for backcountry skiing and because I tend to have issues with sizing jackets over my well developed shoulders. The cut and fit on this is superb - the dolman sleeve gives ample room in the shoulders/armpit area, the princess seamed waist skims down to the hip and the extra high, zip up neck ensures that drafts won't chill your neck. Stoic has somehow made this jacket both roomy AND body conscious. The super-stretchy softshell is faced with an extra-soft fleecing inside. I had my doubts that something this stretchy could be truly windproof, but this jacket has become my go-to for journeys in the Jeep with the top down on cool evenings. Super warm, breathable and comfortable- I get compliments EVERY time I wear it.
