This inflatable cover, or bladder, is made of white PVC and goes between the water and the cover of your spa.

Inflate the cover and put it on the water (under the cover), and it will help your water retain heat by adding an extra layer of insulation in the spa and prevent the cover from sagging so the rainwater can run off.
