In the present paper, we investigate the determinative conditions for the isothermic Hopf cylinders and Hopf tori of spherical helices which are the tangent indicatrices of slant helices. Based on the relationship between geodesic curvature and principal curvatures, the characterizations are obtained by blending the results of inspired references.
