I purchased these as a replacement for the more expensive Jockey brand, and was a little bit disappointed with them.  They fit looser than the Jockeys, so not as much support from them.  The material is thin, and was comfortable, but I will be going back to Jockey brand.  I did get lucky, the local Meijer store had a Jockey off brand and I purchased and tried them, and they are the same as Jockey, so I will be buying them there from now on.
