The invention relates to a tube comprising a heterophasic polypropylene composition comprising a heterophasic polypropylene copolymer with an antioxidant comprising a sterically hindered phenol. The heterophasic polypropylene copolymer has the relative amount of crystal line polypropylene above 20 wt %. the relative amount of xylene cold solubles (XCS) fraction is at least 10 wt % and the relative content of isolated ethylene sequences (I(E)) of the XCS fulfills the equation: I(E)
