Elastomeric monofilament exhibiting improved long term retention of strength and elongation after exposure to test conditions described by SAE J-1885 are disclosed. The monofilaments comprise in specified amounts as weight percents on weight of monofilament: (1) at least one elastomeric copolyester polymer, and a stabilizing system comprising: (2) at least 1% carbon black, (3) at least one antioxidant, (4) an oligomeric hindered piperidinyl (HALS) compound having a pKa of less than 7 or a pKa from 7 to 12 in combination with an acid scavenger, and (5) a UV stabilizer other than a hindered piperidinyl (HALS) compound. The preferred embodiment is a heterofilament wherein the sheath copolyester has a lower melting point than the core and contains (4) according to: as specified.
