I had been a loyal J.C Penney underwear guy for years.  A couple of years back the quality of their products took a serious downturn.  I attributed this, in part, to the place where they were manufactured, i.e. Pakistan versus Honduras or the U.A.R.  Next, I tried Jockey, but found the unusual fly design uncomfortable.  Additionally, they have a very high cut on the leg openings that one cannot ignore throughout the day.  Otherwise, their quality is good. Fruit of the Loom was next and they were very good except for their sizing ( S, M, L ).  At 5' 8" and 175lbs. mediums were too tight but large was just a tad too big.  Fortunately, they shrunk a a little with laundering.  The Dockers (36) are PERFECT.
