<p>The present invention relates to a cold-drawn breathable film formed from a blend of a soft polymer component and a hard polymer component. The soft polymer component (SPC) is a copolymer of a major olefinic monomer and a minor olefinic monomer. The major olefinic monomer is either ethylene or propylene and forms the majority of the SPC. Preferred films after cold-drawing exhibit a water vapor transmission rate (WVTR) of at least 100 g-mil/m2-day.</p>
