These are really fantastic shirts!  I would say they were made to compete with UA's HeatGear shirts.  I would have given this shirt 5 starts but after years of wearing HeatGear shirts, this SCOTTeVEST shirt's material feels thick on the front and normal on the back for a hot weather shirt.  Because of that the front does hold in more heat than the HeatGear.  But this shirt has extra pockets...two to be exact, not three.  One on the left shoulder and one by the right hip that is, well, imagine one long pocket but bent.  At the part that bends is the zipper.  So you "can" consider it two pockets but really it is just one.  Compared to UA's HeatGear.  Pros: Looks better and more professional.  Has pockets.  Doesn't gather lint in the dryer like the "charged static" on UA's HeatGear that many of us HATE.  Cons: Warmer up front which leads to feeling warmer in general.  My opinion?  These shirts are worth it.  I would recommend them!
