Sun2Solar 1200 Series Blue Round
Best overall / best above-ground round — The most popular solar blanket for a reason: a 12-mil blue bubble cover that traps heat and cuts evaporation, in round sizes from 8 to 33 feet. Blue transmits some sunlight and reflects the rest, the balanced all-around choice; light enough to pull off without a reel. Trim-to-fit without voiding the warranty.

Pros
- 12-mil blue: the balanced heat-and-durability middle of Sun2Solar's line
- Traps heat (up to ~15°F) and cuts evaporation ~95%; light enough to remove by hand
- Trim-to-fit to any round pool without voiding the warranty
Cons
- Not for you if you want the thickest, longest-lived cover — that's the 16-mil 1600 series
- A solar cover is NOT a safety or winter cover — it does nothing over the off-season and holds no weight
- Bubbles degrade in sun; expect ~2–3 seasons of real life regardless of the warranty term
About one season before it turns brittle and falls apart, with seams separating; a warranty replacement still cost one owner the shipping. It also will not warm a pool on its own — it slows heat loss.

“This is really nice. Light easy to take on and off. Definately holds the heat in. I recommend and would purchase again.”— shelly steele, Amazon · Verified owner
Pro review “We tested the 18-foot Sun2Solar 1200 Series Crystal Clear Round Cover, and it proved to be top quality during testing. We liked that it was very easy to put on the pool but still thick enough to be durable (12 mils).”Best Overall of 10 solar covers tested (fit, one-hour sun heat gain; Ease, Durability, Performance and Value all 5/5). What differs: they tested the CRYSTAL CLEAR colourway of this same 12-mil 1200 Series; we card the BLUE. Clear passes more sun for heat gain, blue holds heat better overnight and hides debris — the build, thickness and fit they praise are the same cover.— Tom Scalisi, Timothy Dale, Bob Vila
