Quick verdict
For inground pools, the Sun2Solar Blue 24 ft Round is my top pick. Its 12-mil blanket is designed to raise water temperature by up to 15 degrees, retain heat after sunset, and cut evaporation by up to 95 percent while keeping debris out.
VEVOR Solar Pool Cover
This VEVOR cover is a 32 by 16 ft rectangle in a thick 16-mil bubble design with thousands of micro bubbles for dual heat retention. VEVOR states it reduces water evaporation by up to 95 percent, fits inground and above-ground pools, and is made from durable PE that resists stretching and tearing.

Why you should trust this guide
I compared these solar covers using their stated mil thickness, heat and evaporation claims, materials, and sizing rather than assuming one brand is best. Solar covers, sometimes called solar blankets, all work on the same principle of trapping the sun’s heat in the water and slowing evaporation, so the meaningful differences come down to thickness, size, and how each is meant to fit your pool. I have not floated these covers on a pool myself, so my notes rest on documented specifications, and I kept the manufacturers’ up-to numbers as claims rather than guarantees.
My aim is to help you match a cover to your pool’s shape and your climate, not to chase the highest temperature claim. A cover that is the wrong shape or too thin for heavy sun exposure will disappoint no matter what its listing promises, so I focused on fit and durability alongside the heating numbers. Where covers are designed to be cut to shape, I noted that, since it is a one-time decision.
How we evaluated
I looked first at mil thickness, because it is the closest thing to a durability rating for a solar cover. The 16-mil VEVOR covers are noticeably thicker than the 12-mil Sun2Solar and VINGLI options, which generally means longer life and more resistance to tearing, though even thick covers need careful handling. Thickness also correlates loosely with how well the bubbles trap heat.
Then I weighed size and shape against fit. Round covers suit round pools, while the rectangular VEVOR and VINGLI covers are designed to be trimmed to any shape, which adds flexibility but makes accurate measuring important. Heat-gain and evaporation claims, debris protection, seam construction, and whether a reel is recommended for handling rounded out the comparison. I treated the temperature and evaporation figures as up-to claims rather than guarantees, because real results depend heavily on your climate, how much direct sun your pool gets, and how consistently you keep the cover on the water when the pool is not in use.
Handling also factored into my thinking, since a solar cover only helps when it is actually on the pool. Large covers are awkward to drag on and off by hand, and a cover that is a chore to manage tends to sit rolled up in a corner. That is why several makers, including VINGLI, recommend pairing their blankets with a matching reel, and why I noted handling alongside the heating numbers.
What to look for
- Mil thickness: thicker covers, such as 16-mil versus 12-mil, generally last longer and resist tearing better.
- Size and shape: match a round cover to a round pool, or choose a cut-to-fit rectangle for irregular shapes.
- Heat retention: look for stated temperature gains and overnight heat trapping to extend your swim season.
- Evaporation control: covers that block up to 95 percent of evaporation cut water and chemical loss.
- Material and seams: durable PE with strong welded seams holds up better through a full season of sun.
- Cut-to-fit design: a trimmable cover adapts to odd shapes, but measure carefully since it is permanent.
- Handling and reels: larger covers are easier to manage with a matching reel, which some makers recommend.
A solar cover is one of the cheapest ways to warm a pool and stretch your swimming season, and it pays back further by cutting evaporation, water use, and chemical loss. The right pick depends mostly on your pool’s shape and how thick a cover you want for your sun exposure, so measure your pool, decide between a fitted round cover and a cut-to-fit rectangle, and choose the mil thickness that balances longevity against cost.
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking. When we have not used a specific model first-hand, we say so.

What to look for
Mil thickness for durability
Thickness is the rough durability measure for solar covers. The 16-mil VEVOR covers are thicker than the 12-mil Sun2Solar and VINGLI options, generally meaning longer life and better tear resistance.
Match the shape to your pool
Round covers like the Sun2Solar suit round pools, while the rectangular VEVOR and VINGLI covers are designed to be cut to fit any shape. Measure carefully before trimming, since it is permanent.
Heat gain and retention
Solar covers warm water by day and hold heat at night. The Sun2Solar claims up to a 15-degree rise, and the bubble designs trap warmth after sunset to extend the swim season.
Evaporation and chemical savings
Every cover here claims to cut evaporation by up to 95 percent, which reduces how often you top up water and how much chemical is lost to the air over a season.
Handling and storage
Larger covers are unwieldy to move by hand. VINGLI recommends pairing its blanket with a matching reel, which makes rolling the cover on and off far easier.
Our verdict
For inground pools, the Sun2Solar Blue 24 ft Round is my top pick. Its 12-mil blanket is designed to raise water temperature by up to 15 degrees, retain heat after sunset, and cut evaporation by up to 95 percent while keeping debris out.
FAQs
Claims vary, but the Sun2Solar cover is stated to raise water temperature by up to 15 degrees using solar energy. Actual gain depends on sun exposure, pool size, and how consistently you keep the cover on, so treat these as best-case figures.
Mil measures the cover's thickness. Thicker covers, like the 16-mil VEVOR options, generally last longer and resist tearing better than 12-mil covers, though even thick blankets need careful handling to avoid punctures at the edges.
Many are designed for it. The rectangular VEVOR and VINGLI covers can be trimmed to any pool shape, which is handy for irregular pools. Measure carefully first, because cutting is permanent and cannot be undone.
Yes. By floating on the surface, these covers reduce evaporation by up to 95 percent according to their makers, which means less frequent topping up and less chemical loss, since evaporation carries away both water and sanitizer.
The bubble side faces down toward the water so the bubbles trap heat against the surface, and the smooth side faces up toward the sun. Following the maker's instructions ensures the cover heats and insulates as designed.
