Warm and soft
I am a petite with a curvy, athletic build and bought this top in a large. It is long, which is good because it doesn't come untucked from my snowboard pants, but luckily the shoulders and sleeves fit appropriately. The fabric is quite soft and very comfortable. I use this as a medium-weight layer and have found it to be great for riding on cold days (0-30 degrees F) as a base layer under my snowboard pants and fleece-lined jacket. It also performs pretty well during aerobic activity (i.e. hiking, snowshoeing) on cold days-- I don't end up clammy after sweating. Finally, the pattern (blue and green on a cream background) is stylish enough that I don't worry about wearing it apres.
