I find these polos to have the right amount of tapering without feeling confining or restrictive.  I appreciate that the tapering doesn't creep into the chest, neck or arm areas... it stays comfortably in the mid-section.  I also appreciate that IZOD showed restraint in the size and prominence of their logo (as opposed to other clothing designers that feature gaudy, unavoidable logos on their products).  My only critique is relatively minor: the tags around the neckline are very scratchy and not easy to remove.
