Thermal Foam Spa Blanket.

The cover works well and is easy to put on and take off

Happy with the cover, it has assisted in keeping the water at temperature during very cold nights; long term hoping that it saves the inside of the cover from degradation from the off gassing of chemicals. The only negative is that they dont come pre-cut templated for common models such as the Master Spa15D; I am not much at the arts and crafts of cutting to fit and would have paid a premium for a templated pre-cut cover..

Extremely easy to use…cut it to the perfect shape in a few minutes. Increased efficiency with our tub!
