Perfect in almost every way. The small is spot-on for my wife. Couldn't have asked for a better fit. She's 5'-4", 135ibs with curves. The fit hugs, without being tight. The fabric is magic. I have the Henderson and we agree it's amazing at keeping you warm when cold (and sweaty), and comfortable even when the temps warm up. It's great for xc skiing in winter and hiking in spring through fall in all but full summer heat, although it is dry here. Probably wouldn't reach for it in humid conditions. Only wish is for a small zip stash pocket somewhere. Great layer.
