The crossing relation for the product of transversity amplitudes is considered for all different mass cases. It is shown that any product of transversity amplitudes, such that the product is free from kinematic singularities and zeroes at those thresholds and pseudo-thresholds which do not coincide with the boundary of the physical region, has a very simple crossing relation: it is equal to the corresponding crossed-channel product up to a constant phase factor. The relations among the crossing angles are discussed.
