## Description

The Pool Mate Heavy-Duty Blue Winter Pool Cover will protect your pool from winter elements. This is a solid winter pool cover that will not allow water to pass through its material. The Pool Mate Heavy-Duty Blue Winter Pool Covers is constructed of heavy-duty polyethylene. All seams are heat sealed for better performance. The blue topside of this pool cover is coated to prevent UV damage. Please order by your pool size, as the overlap goes beyond the pool size listed. This cover includes a four-foot overlap. If you have a very large top rail, please consider a larger pool size. This cover should be able to comfortably float on the pool water without excessive stress. This cover is not meant to be used as a debris cover during the swimming season. This winter pool cover is intended to be used during the off-season. This cover is meant for traditional above ground pools with a traditional top rail. Includes a winch and cable that should be used to secure your pool cover through the grommets around the perimeter of the pool cover. For extra securing, cover clips and cover wrap (both sold separately) are suggested for pool closing. No other method of installation is recommended..

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great cover
*by M***N on August 29, 2025*

Great cover for my pool. Unfortunately the price has doubled in the last couple of years.

### ⭐⭐⭐⭐⭐ Terrible Experience
*by J***N on December 1, 2020*

The tarp lasted less than two months before tearing. Manufacturer said it’s normal wear and tear due to being in the open. Don’t waste your money on a company with such poor customer service and value.

### ⭐⭐⭐⭐ Quality issue- now resolved
*by C***N on September 2, 2025*

We didn’t notice that we had a defective eyelet until it was already on the pool. Waiting to see if the warranty department will help us. I will update my review if they fix the problem.UPDATE- The manufacturer is replacing it. Great customer service!
