These are very nice - so nice that I immediately ordered another 4 after receiving my first order. They are very comfortable and fit well.

UPDATE 2012-04-23: I'm reducing my rating to 4 stars because threads have started breaking and unraveling several months ago. I clip the loose threads with nail clippers and the underwear is still very comfortable, wearable, and is still my current favorite, but the quality is not what I had originally thought, though I'd still say is at least "good".
