You could call the Consejo Nacional de Zonas Francas. They could assist you to find the free zones that manufacture the kind of t-shirts you are looking for. We are providing below a list of free zone industries, but note there are many non-free zone manufacturers in the city of Santo Domingo. For an example of quality of one of these, visit the XR stores in Santo Domingo (Plaza Fern?ndez, for example).
