Gen2 by GeoBubble
The Graphene-Enhanced Gen2 Material

Stronger by design.
Warmer by performance.

Crystal-clear Sol+Guard™ transmits 80% of the sun's energy directly to the pool water, while graphene nanoplatelets blended throughout the polymer reinforce the cover from within.

  • Maximum solar gain
    Designed to maximize solar energy reaching the water, helping raise pool temperatures by up to 14°F.
  • Stronger durability
    51% higher puncture resistance and 24% higher tear resistance than a conventional 20-mil cover, demonstrated through university tensile, tear and impact testing.
  • Lighter, easier handling
    The ease of a 16-mil cover with the strength of a 20-mil — more flexible, easier to handle and less prone to fold marks.
  • Lower environmental impact
    20% less polymer means a lower carbon footprint in manufacturing, and the material stays 100% recyclable.

How It Compares

Not all bubbles are created equal.

If your last solar cover turned brittle or began falling apart after a season or two, traditional round bubbles may be part of the reason. Their shape concentrates stress at vulnerable points, while the patented GeoBubble™ design distributes stress more evenly across the material.

2025 Heated-Pool Testing

Two identical pools. One clear difference.

In a 23-day side-by-side test of two identical 11,000-gallon heated pools, Gen2 Sol+Guard™ consistently outperformed Sol+Guard™ 500. Both pools reached an 82°F daily high within two days, but Gen2 went on to peak at 92.7°F and maintained temperatures nearly 2°F warmer on average through cooler conditions.

What Could Your Pool Save?

The pool cover that pays for itself.

An uncovered pool loses more than water. Evaporation drives up heating, water and chemical costs every day. Gen2 Sol+Guard™ helps reduce those losses — saving an average pool thousands of gallons of water each year, with even greater savings in hot, dry climates. If you heat your pool, the savings can add up even faster.

Built To Outlast

Engineered to outlast every bubble cover you've owned.

Traditional bubble covers can become brittle, tear and eventually shed plastic into the pool as they break down. Gen2 Sol+Guard™ is engineered differently — from its patented GeoBubble™ shape to graphene reinforcement throughout the material — to better resist the stress, UV exposure and pool chemicals that cause premature failure. And with material rated to -13°F, it's built to stay on the pool through the off-season, extending that protection beyond summer.

Answers Before You Ask

You've got questions, we've got answers.

What does graphene actually do in the cover?
Graphene nanoplatelets are blended through the polymer itself, reinforcing the material from within. The result is 51% higher puncture resistance and 24% higher tear resistance than a conventional 20-mil cover — from a lighter 16-mil that uses 20% less polymer, and is easier to roll, fold, and handle every day.
How much warmer will my pool get?
Gen2 Sol+Guard™ is engineered to raise water temperature by up to 14°F — its crystal-clear material transmits 80% of the sun's energy straight into the water, while the insulating air cells hold the heat you've gained by stopping overnight evaporation loss.
Do I need a pool heater for this to work?
No — sunlight alone warms your pool by up to 14°F. Have a heater? Gen2 Sol+Guard™ reduces that energy use by over 70%, lowering your pool heating costs.
Can it extend my swim season?
Yes — up to 14°F of solar gain plus overnight heat retention adds weeks of comfortable swimming on both ends of the season, without touching a heater.
How does color affect performance?
Clarity is the performance. Gen2 Sol+Guard™'s crystal-clear material lets visible light and infrared pass straight through to heat the water and the pool shell below — the fastest free heat gain of any GeoBubble™ cover. Graphene helps spread that warmth across the cover and into the water. Want algae control built in? That's EnergyGuard™'s job.
Why does my pool lose all its heat overnight?
Evaporation is the number one cause of pool heat loss — responsible for up to 70% of it — and Gen2 Sol+Guard™ eliminates 98%+ of evaporation. The insulating air cells hold the day's warmth through the night, so you're not starting cold every morning.
Will this lower my water bill?
Yes — by eliminating 98%+ of evaporation, Gen2 Sol+Guard™ saves an average pool roughly 8,500 gallons of water a year, and more in hot, dry climates where loss is highest. That's why it carries the Smart Approved WaterMark.
Can it reduce how many chemicals I use?
Yes — covered pools use up to 40% fewer chemicals. Less evaporation means treated water stays in the pool, and less debris and UV exposure mean your chemistry stays balanced longer.
Does it work on shaded pools?
Yes — even in partial shade, evaporation is still your pool's biggest heat thief, and Gen2 Sol+Guard™ eliminates 98%+ of it while its insulating cells hold the warmth your pool does collect. You'll see less solar gain than a full-sun pool, but the retention benefits work in any light.
How long will it last, and how do I care for it?
GeoBubble™ covers are engineered for an 8+ year product life — 3–4× longer than a traditional pool cover.* Care is simple: keep it on the pool whenever you're not swimming, store it under the included reflective storage sheet when it's off, keep your water chemistry balanced, and never re-cover the pool right after a shock treatment. For effortless daily handling, add Rocky's Reel System.
Can I leave it on through the off-season?
Yes — Gen2 Sol+Guard™ is rated to -13°F, so freezing temperatures won't crack or damage it, and it keeps blocking evaporation and debris while the pool is out of use. As a clear solar cover, it doesn't filter the light algae need — keep your water balanced through the off-season.
How do I choose the right size?
Just measure your pool's widest and longest points and order the size that fills the entire area — any excess trims easily for an exact fit.
What if I have an unusual pool shape?
No problem. Order for your widest and longest points, then trim the excess — our custom-fitting video shows how easy it is.
Will it work with my existing reel?
In most cases, yes. GeoBubble™ covers roll onto standard solar cover reels, and the Floating Leading Edge trims to your exact width for a DIY fit on new or existing covers.
Is it safe for my pool type?
Gen2 Sol+Guard™ is suitable for chlorine & saltwater pools, in-ground or above-ground.
Is this a winter or safety cover?
GeoBubble™ covers are solar blankets, designed for warmth and efficiency. They are not safety covers and are never a substitute for a barrier, fence, or supervision.
