PROBLEM TO BE SOLVED: To provide an elastomer composition excellent in moldability and scratch resistance e.g. as a material of a cover etc., of an airbag loaded on an automobile etc. SOLUTION: This elastomer composition comprises 30 to 100 pts.mass of a hydrogenated product of a tetrablock copolymer containing (A) a polymer block of a styrene-based compound and (B) a polymer block of a conjugated diene compound, 0 to 70 pts.mass hydrogenated product of the triblock copolymer containing the above (A) and (B), 5 to 100 pts.mass mineral oil-based softening agent based on the 100 pts.wt. total of the hydrogenated product of the tetrablock copolymer and the hydrogenated product of the triblock copolymer and 0 to 60 pts.mass polypropylene, and having a 70,000 to 500,000 range weight-average molecular weight of both of the hydrogenated product of the tetrablock copolymer and the hydrogenated product of the triblock copolymer and a≥20 mass% styrene content in both of them.
