I/G 6' O/L Premium HD Winter Cover
 
Protect your swimming pool with the new Premium HD Winter pool cover! Made with the heaviest-duty strongest rip-proof polyethylene fabric used in pool covers, the tan material is reinforced with 14 vertical and horizontal threads per square inch, with 50% stronger material that is also lighter than other comparable covers, and premium-quality marine-grade 1 1/2" binding along the perimeter of the cover to protect against wear and tear. The top side of this winter cover has been treated to reflect UV rays, and the bottom of this winter cover is black to prevent algae growth in your pool. Use water bags to secure the pool cover in place during closing (not included).
