The invention relates to a composition comprising (A) a heterophasic propylene copolymer and (B) an elastomer of ethylene and α-olefin comonomer having 4 to 8 carbon atoms, wherein the heterophasic propylene copolymer consists of (a) a propylene-based matrix, wherein the propylene-based matrix consists of a propylene homopolymer and/or a propylene copolymer consisting of at least 70 wt % of propylene and at most 30 wt % of ethylene or an α-olefin having 4-10 carbon atoms, based on the total weight of the propylene-based matrix and wherein the propylene-based matrix is present in an amount of 60 to 95 wt % based on the total heterophasic propylene copolymer and wherein the propylene-based matrix has a melt flow index of at least 0.1 dg/min and at most 45 dg/min, measured according to ISO1133 (2.16 kg/230° C.) and (b) a dispersed ethylene-α-olefin copolymer, wherein the dispersed ethylene-α-olefin copolymer is an ethylene-propylene copolymer, wherein the ethylene-α olefin copolymer is present in an amount of 40 to 5 wt % based on the total heterophasic propylene copolymer and wherein the sum of the total amount of propylene-based matrix and total amount of dispersed ethylene-α-olefin copolymer is 100 wt %, wherein the amount of ethylene in the ethylene-α-olefin copolymer of the heterophasic propylene copolymer is from 10 up to and including 45 wt % (RCC2) (B) an elastomer of ethylene and α-olefin comonomer having 4 to 8 carbon atoms wherein the elastomer has a density in the range from 0.88 up to and including 0.907 g/cm3.
