Fibers made from formulated ethylene polymer compositions are disclosed. The ethylene polymer compositions have at least one homogeneously branched linear ethylene/&agr;-olefin interpolymer and at least one heterogeneously branched ethylene polymer. The homogeneously branched linear ethylene/&agr;-olefin interpolymer has a density from about 0.905 to about 0.92 g/cm3 and a slope of strain hardening coefficient greater than or equal to about 1.3.
