Great quality shorts.  Love these things!  I own 5 pairs of them and they are bullet proof...  I've had a few of my pairs for years.  Eventually the inner seems rip (though I have sewn them back up), but I run at least 5 miles a day every day, and these shorts never give me issues.  They stay put and prevent chafing.  The inner seam ripping was literally after years of use.
