They were great for the first 4 hours I owned them.  I noticed a two-inch tear at the seam on the inside lower leg after less than 4 hours of wear laying on the couch.  The stitching just came undone.

I was all set to keep them, because they were very comfortable.  Aside from the tear early on, they are quite thin and about 3 inches too long.  I'm 5'11".  That didn't bother me too much.  True to size in the waist.  I'll try some other brand or style...
