I purchased these along with the Champion Men's Tech Performance Boxer Brief.  These have some cotton and are very nice, but the Tech Performance seem to be a little nicer.  These do not stretch out of shape and they fit properly all day.  I probably will not order the "long" version of these again.  They are bit long on the thigh and I'm 6'4".  This the only reason for 4 stars instead of 5.  I plan to order these again in the regular/standard length.  Very nice boxer briefs that I do recommend.
