Nicely made, sharp looking shirt.  If used during athletic activity it is quite comfortable and cool as the Dri Power claims.  It also is wrinkle free.  But the bad thing, being 100% polyester, is almost any activity, even just standing around in slightly warm conditions, it quickly reeks of sweat.  You feel comfortable and dry, but the smell is not good.  So for any casual wear it isn't a great choice.  A shame really.
