Puri Tech Bulldog, Winter Air Pillow, Inflatable - 4 x 8 ft

This pillow is 4 x 8 foot to ensure cover stays separated from water to prevent freezing.

Winter Air Pillow also prevents cover from holding water, snow, or debris on the top. When your pool water freezes, Air pillow absorbs freezing water and compresses to relieve the stress and pressure from the walls of your above ground pool. 

Air Pillow also lifts your winter pool cover out of the water to prevent it from freezing in the water and to protect it from tearing. 

We want your pool cover to last as long as possible.

Inflate pillow halfway, to allow for expansion in freezing conditions.
