Xton's Golf Green Covers are made of a woven polypropylene material, which is a proven protective barrier against sun, wind, and harsh temperature. Our fitted covers are made rectangle in shape with custom dimensions that correspond to the particular green being covered. All perimeter seams are reinforced with black tape to resist abrasion against normal wear. Perimeter straps run alongside our covers every 12 feet and are used to position and anchor the green cover with our 10” yellow stakes. All straps are sewn with reinforced 1-1/2 inch box tacks.
