These are great.  They are comfortable, and lightweight.  I wore them under other pants in the winter for added insulation.
Cons:
I had hoped that they would be more opaque.  They are opaque to a degree, but they are too thin for me not to wear them under a dress or an especially long tunic top (sort of like I would wear with tights).  I give them 3 stars because I had hoped to have more versatility with them in the warmer months.
