Familiarity: I've put it through the wringer
These were awesome for use in 40 degree weather. My only complaint is that they pill really badly, so I hang dry to extend the life. I have heard a few stitches tear if I'm not careful putting them on, so get the sock fitted to the heel before pulling the tops up.
