MADHOLLY Spa and Hot Tub Cover - 7 FT Dia 16-mil Round Hot Tub Thermal Insulation Solar Blanket Bubble Cover

Trim to Fit: Our thermal solar blanket cover is 7ft in diameter and fits most inflatable round style hot tubs. If your tub has more irregular shapes, you can put the cover over the hot tub first, then make a mark and cut along the mark. (Tips: The cover may have creases from folding. Lay it flat and place heavy objects on top for a few hours to help it flatten out).

16 MIL Thickness: Different from the general 8-12 mil spa hot tub solar blanket, we use a thicker material of 16 mil, which has better heat preservation and water retention effect, the bubbles will not crack or fall off, and the round solar cover can be used for a long time.

Save Time & Money: When you heat the water in your hot tub, putting our thick bubble hot tub cover on it can greatly shorten the heating time, and it also saves you money to some extent. Besides, using the blanket cover can effectively cut down the condensation on your hot tub cover.

More Functions: Covering the round solar cover on the hot tub can not only effectively prevent up to 95% of water evaporation loss, but also maintain the water temperature and absorb the heat energy of the sun's rays to heat the water, reducing the time you need to heat the water next time.

Bubble-side Down: When using, you need to put the bubble side of the solar blanket for hot tubs close to the water surface, with the smooth side facing up, which can also play a role in preventing dust, reducing condensation and freezing on the edge.
