Pool Mate 21ft Premium Tan Winter Pool Cover for Above Ground Pools

Our review of the Pool Mate 21ft Premium Tan Winter Pool Cover finds it best suited for owners of 21 ft round above-ground pools who want a heavy, simple winter seal. The standout reason to buy is its extra 4 ft overlap and included winch and cable, which make installation easier than typical covers; in practice the cover size measures 25 ft including overlap, so it fits over rails and decks more comfortably. This reviewer found the solid tan material and heat-sealed seams give a reassuring feel of protection, though long-term durability reports from users are mixed.

Key Features

• 4 ft overlap: Provides extra material beyond the pool edge so the cover is easier to install and can fit pools with larger top rails.
• Included winch and cable: Makes securing the cover through the grommets straightforward and reduces the need for separate hardware purchases.
• Solid, non-permeable material: Prevents water from passing through, keeping winter debris and runoff out of the pool.
• Heavy 5.2 oz/yd2 polyethylene: The thicker fabric and 14 x 14 scrim indicate stronger resistance to tears and punctures compared with lighter covers.
• 20-Year Warranty: Backed by an industry-leading warranty, giving buyers long-term confidence in the construction and seams.
• Tan UV-coated topside: The coated surface helps resist sun damage in early/late season exposure and extends cover life.

Who It's For

This cover is aimed at homeowners with a 21 ft round above-ground pool who want a solid winter barrier and an easier installation. The 4 ft overlap and included winch are particularly useful for those with partial decks or large top rails who need extra material to route the cable and anchor the cover reliably.

Those who should look elsewhere include buyers seeking a water-permeable debris cover or a lightweight seasonal tarp for occasional use; also, customers prioritizing flawless long-term performance in every review have reported mixed longevity, so heavy-use buyers who need absolute assurance year after year may prefer to compare multiple heavy-duty options.

Pros & Cons
