I have done my homework  and Global Syn Turf has the most advanced artificial grass technology I have seen yet.  Their selection of polyethylene synthetic turf material is more advance that most artificial turf.  The density, filament and fiber shape is truly engineered.  All of these elements together create a very unique and realistic artificial grass.  I am a landscape architect in the Florida and I have seen so many different skus of artificial turf, but Global Syn Turf makes the best products I have seen.
