Your above ground pool cover is tasked with fighting a constant battle against evaporation, UV radiation, and wind, and the difference between a relaxed spring opening and a disaster cleanup often comes down to a single number: the scrim count or mil thickness of the material you chose.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. To build this guide, I analyzed dozens of product specs, warranty claims, and long-term owner feedback to find which covers actually survive the winter and which fall apart before the first snowmelt.
After comparing material densities, grommet reinforcement methods, and multi-season durability reports, I have identified the seven covers that offer the best protection for your investment. This review of the best above ground pool cover will help you choose the one that fits your climate and budget.
How To Choose The Best Above Ground Pool Cover
Choosing the wrong pool cover can mean buying a replacement every single season, or dealing with a pool full of debris come spring. Focus on three core specs: material weight (GSM and scrim), thickness (mils for solar covers), and the quality of the edge reinforcement around the grommets.
Scrim Count and GSM Determine Lifespan
The scrim count tells you how many threads run through each square inch of the fabric. A standard budget cover might have a 7 x 7 or 8 x 8 scrim, while heavy-duty winter covers use a 14 x 14 scrim. Higher scrim count means greater tear resistance and longer service life. Pair this with GSM (grams per square meter) around 200 or higher for true winter survival.
Mil Thickness for Solar Covers
Solar blankets use a bubble-wrap-style construction measured in mils (thousandths of an inch). An 8-mil cover is lightweight and easy to handle but wears out quickly under constant UV exposure. A 12-mil or 16-mil cover retains heat far better, resists tearing when you pull it over the pool, and typically lasts two or three seasons longer.
Edge Reinforcement and Tie-Down System
Grommets that tear out in a moderate wind are the most common failure point. Look for double-stitched hem reinforcement, nylon webbing around the perimeter, or an integrated winch-and-cable system. A cover with weak edge construction will fail regardless of how heavy the center fabric is.

In‑Depth Reviews
1. Planenfux 24ft Round Pool Cover
The Planenfux cover is the most versatile option on this list thanks to its SmartSide Technology, which lets you flip the black side up in summer for solar heating and the blue side up in winter for UV reflection. The 14×14 ripstop scrim delivers 200 g/m² of density, and the triple-layer bonded construction keeps water, snow, and debris out completely. Owner reports confirm it stayed tight through 60+ mph gusts without tearing
The industrial aluminum winch and 3 mm steel cable make the install simple for one person in around 15 minutes. Grommets are rustproof and reinforced, and the material is tested from −40°F to 160°F, covering nearly every continental climate. Multiple owners mention this is the best cover they have owned in nearly two decades of pool ownership
The only downsides are the premium price and the fact that the cover runs slightly oversized, so measure your pool wall carefully. One owner received a size larger than ordered, so double-check the package before cutting or modifying. For year-round protection that doubles as a solar blanket, this is the strongest performer
What works
- Reinforced ripstop weave holds up in extreme wind and snow loads
- Dual-sided design eliminates the need for separate summer and winter covers
- Easy one-person install with quality winch and cable included
What doesn’t
- Runs large; verify fit before cutting
- Price is the highest of the seven covers reviewed
2. BigXwell Solar Pool Cover 16-mil Rectangle
If solar heating performance is your top priority, the BigXwell 16-mil cover is the thickest bubble blanket on this list. The 16-mil construction traps heat more effectively than thinner alternatives, and owner data confirms water temperature jumps of 14°F within just three days of use. The bubble side goes down to capture solar energy and the blue top reflects UV while keeping the heat locked in the water
The material is durable enough to cut with scissors without fraying, making it a strong choice for irregularly shaped pools that need a custom fit. Evaporation reduction is rated above 95 percent, and owners report significantly lower chlorine consumption—one generator dropped from 60% output to 10-20% after adding this cover. It is a floating installation with no winch or tie-down cables
The biggest drawback is the oversized manufacturing: many owners report the cover runs significantly larger than stated, requiring careful trimming. It is also relatively heavy for a single person to handle, especially in larger sizes. If you prioritize heat retention over winter sturdiness, this cover delivers the best thermal performance per dollar
What works
- 16-mil thickness offers market-leading heat retention and evaporation control
- Trims cleanly for custom pool shapes without fraying
- Reduces chemical use significantly per owner reports
What doesn’t
- Ships oversized; expect to cut a few inches off each side
- Heavy to maneuver solo during installation
3. Shop Square Premium Heavy-Duty Winter Cover
The Shop Square Premium is built specifically for brutal winter conditions, with a 14×14 scrim count and a density of 185 gsm that makes it feel more like a commercial-grade tarp than a pool cover. The LDPE coating resists UV degradation even during the colder months, and the extra sealing seams keep out the fine debris that typically turns pool water green by spring. Owners consistently mention that this is the thickest cover they have ever owned
The steel-core cable and specially molded winch create a tight, secure fit around the pool walls, and the royal blue color looks clean and uniform. The cover floats on the water surface and hangs about 18 inches over the edging with a generous overlap. Multiple owners who previously replaced covers every season report that the Shop Square Premium is still intact after two winters
One significant complaint is that the included winch can feel low quality and may need replacement before the cover itself wears out. Owners in very windy regions report the cover blowing off if not supplemented with additional rope and stakes around the perimeter. If you reinforce the tie-downs and upgrade the winch if necessary, this cover will outlast most mid-range competitors
What works
- 14×14 scrim with 185 gsm density resists tears and punctures exceptionally well
- UV-blocking LDPE coating protects pool liner from sun damage
- Steel-core cable and molded winch create a secure perimeter seal
What doesn’t
- Winch quality is inconsistent; some units feel cheap
- May need additional anchoring in high-wind zones
4. In The Swim 8 Mil Standard Round Solar Cover
In The Swim designed this 8-mil solar cover for owners who prioritize ease of daily handling over multi-season longevity. The lightweight polyethylene material rolls and unrolls with significantly less effort than a 12-mil or 16-mil blanket, making it a good fit for anyone with limited physical strength or a pool that needs regular access. Owner reviews confirm that the cover raised pool temperatures from unswimmable to comfortable in under two days
The cut-to-fit design allows easy trimming with scissors, and the large cut size means you will have plenty of material to shape around ladders and steps. Chemical consumption drops noticeably because the cover blocks UV and debris simultaneously, and evaporation reduction keeps your water level consistent through peak summer heat. For short-season use, this cover performs surprisingly well
The biggest risk is durability: multiple owners report the glued seams coming apart within days or weeks of purchase, describing the product as falling apart almost immediately. The 8-mil material, while convenient, will not survive a full winter or heavy hail. Consider this a seasonal use cover rather than a multi-year investment
What works
- Lightest weight option for easy daily removal and replacement
- Raises pool temperature significantly in sunny conditions
- Trims easily to fit irregular pool shapes and ladders
What doesn’t
- Seam integrity is inconsistent; some units separate after a few days
- Too thin for winter use or high-wind conditions
5. VINGLI 12Mil Solar Pool Cover
The VINGLI 12-mil cover sits in the sweet spot between price and durability. Owners report that the thicker material raised water temperature from 68°F to 83°F within a few sunny days, and the strong welded seams resist the peeling that plagues cheaper glued covers. The bubble-side-down orientation captures heat efficiently and the blue top minimizes UV degradation. Multiple owners have used the same cover for two seasons with no tearing
The material is heavy enough to stay in place without constant fussing, but it is not so thick that one person cannot handle it with a reel system. The cut-to-fit design works well for most standard round and rectangular pools, and the dustproof construction keeps out pollen, leaves, and insects. Owners who paired this cover with a pool reel found the daily on-off cycle straightforward
The main drawback is that the actual dimensions run larger than the labeled size, requiring trimming for a precise fit. One owner ordered a 15-foot size and received a 16-foot blanket. The material also takes up more storage space than thinner covers when folded. For a mid-range solar blanket that offers genuine heat gains without breaking your budget, VINGLI is a strong pick
What works
- 12-mil thickness provides noticeable heat retention without excessive weight
- Welded seams are more durable than glued alternatives
- Strong value for the temperature increase delivered
What doesn’t
- Frequently ships oversized; requires trimming
- Bulky to store when not in use
6. VEVOR 12Mil Solar Pool Cover
The VEVOR 12-mil cover delivers impressive heat retention considering its cost. Owners describe it as thick, sturdy, and easy to cut to size, with the welded seams holding up well through a full season of daily use. The bubble layer reduces evaporation by up to 95 percent, and the PE material blocks most leaf and dust debris from entering the pool. Multiple owners mention that the pool temperature stayed within 2-4°F overnight, reducing the load on pool heaters
The material folds and rolls readily for storage, and the cut edges finish cleanly when trimmed with scissors. One owner successfully installed this cover solo using a pump to remove standing water from the top. The blue color looks clean and helps absorb solar energy effectively. VEVOR covers are known in the gardening space for solid quality at a fair price, and this pool blanket follows that reputation
Some owners note that the cover is heavier than expected, making it more difficult to unwind and wind onto a reel. The weight, however, means it does not blow around in the wind as much as lighter blankets. The aesthetic is purely functional and lacks the refined look of pricier brands. For a no-fuss solar blanket that prioritizes thermal performance, VEVOR earns its place
What works
- Excellent overnight heat retention within 2-4°F of daytime temp
- Welded seams prevent the peeling failures seen in glued covers
- Heavy enough to resist wind uplift without additional anchoring
What doesn’t
- Heavier than advertised; overhead handling is tiring
- Plain appearance with no decorative elements
7. Robelle 24ft Winter Pool Cover
Robelle has been making pool covers since 1973, and this Value-Line model reflects decades of experience focused on ease of installation. The 4-foot overlap means the cover extends well past the pool edge, making it forgiving if your measurements are slightly off. The standard polyethylene material weighs 2.36 ounces per square yard with an 8×8 scrim, and the included winch and cable system lets you tighten the cover securely around the perimeter
For regions with mild winters or for first-time pool owners who want to test the winter cover process without a large investment, this cover works adequately. Owners report that it keeps dirt and leaves out during the cold months and is simple to install with two people. The 10-year warranty sounds generous on paper, but be aware that the actual wear-and-tear claims process may vary
The material is noticeably thinner than the heavy-duty options on this list, and several owners report that eyelets start tearing after just a month of use. Multiple reviews mention needing to replace the cover every single season, with some owners resorting to retying the cable to the eyelets to extend use. If you live in a region with heavy snowfall or high winds, you will need to budget for a replacement every year or two
What works
- 4-foot overlap makes sizing and installation forgiving
- Long brand history with decent customer support resources
- Included winch and cable system for simple tensioning
What doesn’t
- Material is thin; eyelets tear after a few months of use
- High replacement rate of one per season for most owners
Hardware & Specs Guide
Scrim Count Explained
The scrim count refers to the number of threads per square inch in a woven winter cover. A 7×7 scrim has 7 vertical and 7 horizontal threads per inch, while a 14×14 scrim has double the thread density. Higher scrim count directly translates to higher tear resistance, better load distribution for snow, and longer service life. Look for at least 12×12 if you expect heavy snow loads.
Mil Thickness for Solar Covers
Solar blanket thickness is measured in thousandths of an inch (mils). An 8-mil cover is lightweight and easiest to handle but may only last one season under full sun. A 12-mil cover offers a good balance of durability and weight, while 16-mil blankets deliver the highest heat retention and lifespan. Thicker bubbles also provide better insulation against nighttime temperature drop.
