I purchased several pairs of these for myself and my daughters.  We are all extremely pleased with the fit and the ease with which they wash.  We just returned from several weeks in Europe/Northern Africa and knew every morning that our underwear would be clean and dry.  Not only are they easy to travel with, they are exceptionally comfortable and stay dry no matter how much you sweat (we experienced several 100 F with 80% humidity days), making them the ideal underwear for everyday.  I have just ordered more so that we can replace our other undies.
