Micro mesh winter pool cover traps the finest silt and debris preventing them from contaminating your pool. Its reflective silver coating on top of the pool cover speeds snow's melting process to minimize the weight of snow on the cover. The micro mesh winter pool cover has triple-reinforced borders with double-stitched hems for superior durability. The hems are stitched with heavy-duty U.V. treated polypropylene thread to resist rot. All pool covers come complete with a heavy-duty vinyl-coated cable, winch, and have a black underside to inhibit algae growth. Please order your pool cover based on swimming pool size; all covers are made to accommodate an 18-inch water drop. 8-Year Warranty (1 Year Full).
