Winter Hot Tub Bubble Blanket - 7x7 FT 16-Mil Square Pool Spa Solar Cover | Heavy Duty Floating Heat-Retaining Thermal Blanket for Cold Weather Insulation & Solar Heating

This product works great . Keeps the pool covered, clean and heated.

This is my second blanket. The first lasted 5 years. Keeps the chemicals and prevents evaporation. No evaporation means the cover doesn’t absorb moisture. Good product.

We had to change to an electric spa heater and it was taking a long time for the spa to heat up. We bought this to see if it would help. It does help, reduces the heat up time about an hour. Better than nothing. It was easy to cut to fit.

Great..I like that it seemed thicker than others I have had easy to cut to size also.

Great solar cover. I cut it to fit my hot tub. I use it as an added layer of insulation for the top of my hot tub water. Worked out just perfectly!!

barely fits an 8 foot hot tub

It has protected our spa from the sun, reduced the chance of algae and helped us control chlorine levels. I'm sorry I didn't purchase this sooner! Our custom spa is a D shape and this insulating cover was easy to trim to size. It also seems very durable. The bubbles in the cover are like very heavy duty bubble wrap and simply float on the water. Although it just slides on/off the water easily, it's so big I found it a bit difficult to align while putting it back in place.

Better than expected! I had to replace my old bubble blanket and thus fur perfectly, it’s thicker then my hot tub store one.
