The NP45 Black is one of the best texturized nylon putting surfaces on the market. Second only to its higher quality counterparts, NP50 and NP55, this product offers natural roll and realistic speeds for a true putting experience. This turf performs best with the high end ceramic infill offered by Synthetic Turf International, but NP45 can also be used without infill, which makes it an ideal indoor/portable putting surface or outdoor batting cage on concrete.
