A nitrile-rubber medical exam glove composed of a glove body which is a flexible layer of nitrile-butadiene rubber. The glove body has a chlorinated first surface forming a donning side of the glove body and an un-chlorinated second surface form-ing a grip side of the glove body. The elastomeric glove also in-cludes a substantially uniform distribution of a release agent dis-tributed over the un-chlorinated second surface of the glove body. The elastomeric glove has: (a) an average thickness of between about 0.03 to 0.12 mm in a palm region of the glove body as mea-sured in accordance with ASTM D3767, procedure A; (b) an un-chlorinated second surface of the glove body characterized by a Surface Root Mean Square Roughness of from about 3.00 ~1/4m to about 6.55 ~1/4m; and (c) a failure rate of less than about 1 percent when the elastomeric glove is subjected to pinhole leak testing generally in accordance with ASTM D5151-06.
