I have been wearing Ex Officio for a few years and decided to try these due to other reviews saying they were just as good but half the price.
NOT EVEN CLOSE!  While the material may be similar these are too small, they ride up and after just one day of wearing the inside of my legs were chafed badly.  I  already ordered 2 more pair of Ex Officio and these are off to Goodwill. Maybe someone else can find a way to wear them comfortably but from now on, I stick with Ex Officio.  Keeping that area nice and comfortable is well worth the extra money!
