was designed for 2 things: as a first cut of fringe around a putting green and as an alternative to the older sand-filled green technology; a fibrillated fiber that expands when brushed like an outdoor field product. When 5 lbs sand/sq ft are added to this turf, the fibrillated yarn will open up. This turf can also hold 5 lbs sand/sq ft, but because it is a texturized yarn, you don’t have to work so hard brushing in the sand, thereby reducing labor in the install process.
