I've been looking for comfortable pants for the summer.  this pants is the answer.  it's comfortable, thin, and yet not to sheer.  this pants a bit loose, i could fit in s.  i usually buy size 8 or 10 for shorts from retailer, so i'll say this pants run big.  the con with this pants is the stitching around the back pockets is not very sturdy.  i found tiny holes on 2 other pairs before i bought mine.
