Would give six stars if they had it.  I'm a turtleneck/mock neck wearer from late fall to early spring.  I always seem to "rebuy" each year because the black fades, the white isn't as white, etc.  These are incredibly soft, and have a heaviness to them without being bulky.  Very well made,,,,,,,, love 'em.  I don't think these will need replacing as often as the others bought from very well known department stores.  Will definitely buy again.
