STI’s NP55 is the upgraded multi-color option of the NP50. It still maintains the natural ball roll and realistic speeds that the NP50 has always been famous for in the golf industry, but the new two-color texturized nylon yarn combination of STI’s NP55 surface offers a natural look and performance that cannot be found anywhere else. The NP55 still features the coveted dense, non-directional cross-stitched construction that is unmatched by any other product. This turf performs best with the high end ceramic infill offered by Synthetic Turf International, but this product can also be used without infill, which makes it an ideal indoor/portable putting surface. When will it be time for you to Experience A Greener World and a better golf game?
