Solar Sun Rings are passive solar swimming pool heating devices, constructed from two layers of UV resistant vinyl
The upper clear layer directs the suns rays onto the bottom blue layer which absorbs about half of the sunlight, converting it to heat
The remaining sunlight filters through the ring into your pool water
Do not over inflate or use as a flotation device
