XXXtreme Winter Cover

Review by Ivy on Sep 23, 2019 Verified Purchase

This cover was recommended by Tom and it is a great cover for my above ground. It withstood the heavy winter and heavy rains we got in PA last year.
I highly recommend this product and highly recommend Pool Factory for all your pool needs they are pleasant and very helpful for a new pool owner like myself. They take my phone calls and emails each and every time. I am very happy that I found the Pool Factory I will be using them for years to come.

Great Quality

Review by Brad K. Pittsburgh on Sep 20, 2019

This is by far the thickest winter cover I have ever had plus the overall quality is excellent. So much better than the others I have used over the years.
