Familiarity: I've put it through the wringer
I'm a big fan of these, but I use them primarily for walking around town during the winter ( about 20 degrees Fahrenheit). They are really well put together and feel amazing to wear compared to synthetic long underwear I've used. I have a size small and typically wear Levi's 30x30 in jeans and they fit me pretty well.
