Closing a pool for the winter, trapping summer heat, or catching autumn leaves before they sink, the right cover turns pool care from a chore into a simple routine. Homeowners juggling snow loads, hot summers, and leaf-heavy trees all need different things from a cover, and this lineup covers all three jobs. The picks below span heavy-duty safety meshes, solar blankets, leaf nets, and a liquid water conserver for anyone who hates wrestling with physical covers.

A Deeper Look At The Lineup
For a rectangular inground pool that needs to sit quietly under snow and dead leaves all winter, this Lynkron cover takes a workhorse approach. The mesh construction (a woven fabric that lets rainwater drain through rather than pool on top) means you do not have to pump standing water off in January, and the green color blends into typical lawn surroundings better than a bright blue sheet would.
Triple-stitched seams suggest solid longevity in regions where freeze-thaw cycles punish lesser covers. Homeowners who anchor the cover with proper springs and hardware will find the installation straightforward, though you will need to buy anchor hardware separately. Compared with the Lynkron Blue version that follows, the only real difference is cosmetic.
Useful Highlights
- Mesh weave blocks sunlight to slow algae growth under the cover.
- Triple-stitched seams handle heavy snow loads on rectangular pools.
- Green finish hides dirt and blends with lawn edges.
- Permeable design eliminates the need for a cover pump in most winters.
Worth Noting
- Mesh does let fine silt through over the season, so expect some cleanup at spring opening.
- Color and fit options are limited compared with the more configurable ColourTree safety cover.
At A Glance
Right Fit For
Homeowners in snowy regions with a standard rectangular inground pool who want a low-maintenance winter cover that drains itself.
Look Elsewhere When
You need a tight size match for a pool with a step section, where the ColourTree Safety Pool Cover’s step-specific sizing makes installation much easier.
Functionally identical to the green Lynkron cover above, this blue variant earns its place for backyards where color coordination actually matters, like pools framed by a blue house trim or a water-feature aesthetic. The mesh weave and triple-stitched build carry over directly, so you are not trading strength for color.
For most shoppers, the choice between this and the green model is purely visual. If your winter landscape already has enough earth tones, the blue finish can look cleaner against concrete decking. Pool owners with heavy oak or maple trees overhead will still need to clear branches before the first snowfall, since the mesh cannot stop a heavy limb.
Standout Benefits
- Matches blue-toned pool decks and modern backyard designs.
- Same reinforced seam construction as the proven green version.
- UV-resistant material handles long off-season sun exposure.
Trade Offs
- Color choice should not drive a purchase over a better-fitting size option.
- Light blue shows pollen staining more visibly than the green sibling cover.
Whose Shelf It Belongs On
Style-conscious homeowners with a rectangular inground pool who want a winter cover that complements blue decking or tile.
Swap It Out When
Your pool has step cutouts or unusual geometry, where the Lynkron Heavy-Duty Winter Pool Cover Rectangle Green’s standard rectangle shape would not sit cleanly without modification.
This is the cover to look at when your winters are genuinely rough, think heavy wet snow, ice storms, and the occasional kid or pet who treats the frozen cover like a trampoline. ColourTree uses a polypropylene mesh (a tough woven plastic that resists stretching) with a reinforced strap system designed to spread load across the whole panel. The 18-by-34-foot cover is sized for a 16-by-32-foot pool, giving you a 2-foot overlap for anchoring.
Step options are a real advantage over the Lynkron covers, since the listing explicitly accommodates left-end, mid-end, and right-end step configurations for both 16×32 and 16×40 pools. That means you can match the cover shape to your actual pool outline instead of letting a rectangle cover drape awkwardly over a step. Installation is more involved than a basic rectangle, so plan a weekend for fit and anchor setup.
Well-Handled Touches
- Reinforced strap system spreads snow load to prevent sagging.
- Step-aware sizing eliminates gaps at the shallow end.
- Polypropylene mesh stands up to UV and freeze-thaw cycles.
- Two-foot overlap gives anchor hardware plenty of bite.
Points To Keep In Mind
- Heavier than the basic Lynkron covers, so a second pair of hands helps at install.
- You will need to purchase anchor hardware and springs separately.

Reach For A Different Pick When
Your pool is a simple rectangle and budget matters more than weight capacity, where the Lynkron Heavy-Duty Winter Pool Cover Rectangle Green handles the job for less.
A leaf net is a different tool than a winter cover, and treating it like one leads to frustration. The In The Swim 24-foot round net is designed to lay over your existing winter cover and catch leaves, sticks, and acorns before they reach the water-blocking layer below. Come spring, you lift the net and a giant bag of leaves comes with it, instead of a soggy mess fused to the cover.
For round inground pools surrounded by deciduous trees, this saves hours of spring cleanup. The net is light enough to install alone, and it stores in a small bag once leaves stop dropping. You will still need a real cover underneath it, so think of this as a companion piece rather than a primary defense.
Real-World Strengths
- Catches leaves before they stain or rot through the winter cover.
- Lifts off in one motion for fast spring cleanup.
- Lightweight and easy to handle solo.
Small Caveats
- Does not block water or sunlight on its own, so a base cover is still required.
- 24-foot sizing fits round pools only, not rectangular layouts.
Who It Suits Best
Homeowners with round inground pools and lots of overhead trees who already own a winter cover and want a simpler fall cleanup.
Consider Something Else When
You have a rectangular pool, where the In The Swim 18′ Premium Blue Round Solar Pool Cover is not a fit either, so look at the ColourTree mesh as a leaf-shedding primary cover.
Solar covers are measured in mils (a mil is one-thousandth of an inch, so 8 mil is roughly the thickness of a heavy plastic bag), and this 8-mil option is the entry point for in-season heat retention. Floating on the surface when the pool is not in use, it lets the sun warm the water during the day and slows heat loss overnight, extending your swim season by a few weeks on either end in mild climates.
The 15-by-30-foot oval shape suits a common above-ground or shallow-end oval pool layout. The thin material is easy to trim with household scissors if you need to fit a slightly irregular shape. Where it falls short is durability, since 8-mil film tears more easily than the 12-mil alternatives that follow.
Practical Pluses
- Trims easily with scissors to match odd pool shapes.
- Lightweight enough to remove and store without a reel.
- Reduces water evaporation during peak summer heat.
Honest Caveats
- 8 mil thickness tears more easily than 12 mil covers, so handle it gently.
- Less heat retention than the thicker In The Swim 18′ Premium Blue Round Solar Pool Cover 12 Mil.
Key Specs
Best Suited To
Owners of oval pools in mild climates who want a low-cost way to stretch the swim season and cut evaporation.
Not Your Match When
You want a longer-lasting cover that holds up to daily handling, in which case the In The Swim 18′ Premium Blue Round Solar Pool Cover 12 Mil is a better fit for round pools.
Stepping up from 8 mil to 12 mil adds real-world durability without making the cover punishing to handle. This round 18-foot solar cover is the sweet spot for most backyard pools, thick enough to resist tearing when you drag it off in the morning, yet still light enough to manage solo with a simple reel.
The blue finish absorbs solar energy to warm pool water, and the cover holds in overnight heat so your heater runs less. Compared with the 8-mil oval option, this one trades a slight weight increase for a noticeably longer service life. The round shape is the catch, so measure your pool carefully before committing.
The Case For It
- 12 mil thickness resists tearing during daily on-and-off use.
- Retains overnight heat to reduce heater runtime.
- Standard 18-foot round size fits many common inground layouts.
Points To Note
- Heavier than 8 mil covers, so a reel is helpful.
- Only fits round pools, not oval or rectangular shapes.
Who Should Grab It
Round-pool owners in sun-heavy regions who want a thicker solar cover that holds up to frequent daily handling across a long season.
A Better Fit Elsewhere
You have an oval pool, where the In The Swim 15′ x 30′ Standard Blue Oval Solar Pool Cover 8 Mil is the matching shape, even if you give up some thickness.
The 24-foot round size fills a real gap in many backyards, since off-the-shelf covers often stop at 18 or jump to 28 feet. This In The Swim cover targets the homeowner with a mid-size round pool who wants consistent heat retention across the swimming season without paying for a custom cut.
Pair it with a basic solar cover reel and the daily routine of pulling the cover on and off stays manageable. The polyethylene build (a flexible, lightweight plastic) trims with scissors if you need to fine-tune the edge for a slightly nonstandard shape. Owners in windy areas should weigh the cover down or use a reel with straps, since the lightweight material can catch a gust.
A Few Highlights
- Common 24-foot size fits mid-size round pools without custom cutting.
- Reduces evaporation during hot, dry stretches.
- Works alongside a pool heater to extend the swim season.
Worth Bearing In Mind
- Lightweight material can lift in strong wind without a reel or weights.
- Thinner feel than the 12-mil In The Swim 18′ Premium Blue Round Solar Pool Cover 12 Mil.
Perfect Match For
Pool owners with a 24-foot round layout who want a seasonal cover that drops straight on with no trimming required.
Skip It When
You live in a windy open-exposure yard, since the BioGuard Smart Shield Water Conserver 1 Quart 4 Pack offers a no-fuss, no-wind alternative for evaporation control.
For pool owners who refuse to wrestle with a physical cover, the BioGuard Smart Shield offers a different angle: pour it in, and a thin invisible film forms on the water to slow evaporation. The four-pack covers a season of monthly treatments for most residential pools.
It is not a replacement for a winter cover, and it does not block debris, but for hot dry summers where water loss is the main complaint, it does meaningful work. You pour, swim, and let the formula dissipate naturally. The honest read is that you trade the heat retention of a real solar cover for a hands-off experience, so think of this as a complement rather than a competitor to the In The Swim solar options.
Benefits That Matter
- No cover to drag on and off every day.
- Reduces water and heat loss during peak summer.
- Four-pack covers a full season of monthly doses.
Potential Drawbacks
- Does not block leaves, dirt, or sunlight the way a physical cover does.
- Less effective at heat retention than a 12-mil solar cover.
Built With In Mind
Pool owners who want a low-effort way to fight evaporation and keep water warmer without buying, storing, or handling any cover at all.
Another Choice May Suit
You want both debris protection and heat retention, where the In The Swim 18′ Premium Blue Round Solar Pool Cover 12 Mil is a stronger match despite the daily on-and-off effort.
What Matters Most Before Choosing an in the swim pool cover
Match The Cover To The Season And Climate
Start by identifying the real job. Winter covers like the Lynkron and ColourTree meshes are built to handle snow load, while solar covers are designed for in-season heat retention. Putting a solar cover on for winter leaves it shredded by spring. Living in a snow-belt region means prioritizing reinforced straps and mesh permeability, while a mild-climate pool can usually get by with a thinner solar film.
Pay Attention To Mil, Mesh, And Material
Mil measures solar-cover thickness, and higher numbers mean longer life under daily handling. Mesh covers use a different rating system based on fabric weight and stitching. Polypropylene mesh is the current standard for safety and winter covers because it resists UV breakdown over multiple seasons. For solar covers, anything below 8 mil is generally too thin for regular use, while 12 mil tends to be the comfort zone for most residential pools.
Size The Cover To The Actual Pool Shape
Round, rectangle, oval, and step-cut pools each have different cover families. Picking the wrong shape forces trimming, which creates weak edges. The ColourTree cover’s step options exist for a reason: a real pool is rarely a perfect rectangle. Measure twice and check the listing’s compatible pool sizes before you buy.
Think About Daily Handling
A heavy cover that lives in a tight backyard without a reel becomes a chore. Solar covers in the 12-mil range can be managed solo with a basic reel, while safety meshes need spring hardware and real anchor points. The BioGuard liquid approach trades physical handling for a smaller evaporation-only benefit, which is the right call for some households and the wrong call for others.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
The most common error is choosing a winter cover based on the listing photo’s color rather than the actual pool dimensions. A cover that is two feet too short in either direction will not anchor properly and can collapse under snow load. Another trap is buying a solar cover at 8 mil expecting multi-season life, when the material typically needs replacement after one or two active seasons.
Where The Extra Money Goes
Higher-tier covers in this category earn their cost through reinforced stitching, UV-stabilized fabrics, and step-aware sizing. The ColourTree mesh’s reinforced strap system, for example, is engineered for genuine weight loads, not just seasonal debris. Thicker solar films like the 12-mil In The Swim hold up to daily on-and-off use where thinner films tear at the fold lines. For one short season, the budget option is fine, but multi-year ownership usually rewards spending up.
Frequently Asked Questions
What Is The Difference Between A Solar Cover And A Winter Cover?
A solar cover floats on the water during the swimming season to trap heat and slow evaporation, while a winter cover is a heavier mesh or solid sheet that goes on at season end to block debris and handle snow load. Using the wrong one for the job leads to early wear or poor protection.
How Long Does A Mesh Winter Cover Typically Last?
Most quality mesh covers, including the Lynkron and ColourTree options above, are designed to last several winters when properly anchored and stored dry in the off-season. Direct sun exposure and standing water shorten that lifespan noticeably.
Can A Solar Cover Replace A Pool Heater?
No. A solar cover reduces heat loss, which means a heater runs less often, but it does not actively warm the water on its own in cool weather. The In The Swim solar covers work best as a complement to a heater, not a replacement.
Is A Liquid Water Conserver As Effective As A Physical Cover?
A liquid conserver like the BioGuard Smart Shield reduces evaporation but does not block debris, retain heat as effectively, or stop algae growth the way a real cover does. It is a useful supplement, especially for pool owners who refuse to use a physical cover, but it is not a direct substitute.
Do I Need A Reel For A Solar Cover?
A reel makes daily handling much easier on any cover thicker than about 8 mil, and it is almost essential for 12-mil film. Smaller pools can get by with a hand-fold approach, but expect cover wrinkles and faster wear at the fold points without a reel.
Wrap Up
The right cover really depends on what your pool faces each season. Snowy climates and shaped pools point toward the ColourTree mesh, mild-climate oval layouts work well with the 8-mil In The Swim, and round pools in sun-heavy regions get the most from the 12-mil round option. For anyone who refuses to handle a cover at all, the BioGuard Smart Shield offers a different kind of solution worth considering. Match the cover to the job, and the rest of the season tends to take care of itself.
