The topological condition for the existence of a $pin^c$ structure on the
product of two Riemannian manifolds is derived and applied to construct
examples of manifolds having the weaker Lipschitz structure, but no $pin^c$
structure. An example of a five-dimensional manifold with this property is
given; it is pointed out that there are no manifolds of lower dimension with
this property.
