PREMIUM CLEAR BLANKET HEATS YOUR POOL FASTER THAN BLACK OR SILVER! Our blankets are laced with air bubbles that act as an insulating layer, shielding your pool from cool winds and nighttime cooling. In addition, our clear blankets allow more solar heat to reach the depths of your pool and heat it thoroughly. Our blankets are made of 12-gauge material so they will outlast most other above-ground blankets on the market. They are backed by a 5-Year Warranty.
