Familiarity: I've used it several times
This shirt is really soft and quite warm, but not clammy, even when working up a bit of a sweat (cross country skiing), and, of course, no odor. The zipper does not snag, and closes up around my neck almost like a mock turtleneck. I wear a size Large and it fits perfectly. It could be tucked in or not, as the length is just right. The material is not itchy, although for a few minutes you might feel it on your neck, but I found this goes away quickly.
